SolidWorks develops medium application in heavy-duty machine product

The design technological process of the tradition of design technological process that suits with SolidWorks software photograph is based on environment of 2 dimension CAD to build, design technological process compares extensive, general component is " functional design, concept design, detailed design " 3 phase, the definition as to every phase and involve working content, experts are defined from what different point of view gave out to differ, without uniform agreement. Get as a result of the application of three-dimensional CAD software the limitation of computer hardware, the design train of thought that is based on three-dimensional CAD software and the design train of thought that are based on software of 2 dimension CAD have very big different, if use three-dimensional CAD software according to planar thinking mode and design technological process, not only cannot reflect a dominant position, the likelihood shows a lot of inferior position instead. Want to produce the advantage of three-dimensional CAD software adequately, must discuss a kind of new design technological process and design mode. The contemporary design thought that is based on SolidWorks place contain and product build modular characteristic, the proposal is design process cent " functional design, concept design, structure design, detailed design, give a project to pursue " 5 phase. The definition that pursues because of the function is designed and giving a project is compared clarity and unified, reason here is not done discuss, the definition of the notional design of three-dimensional CAD mode, structure design, detailed design discusses below. (1) the task of notional design phase is to decide the positional relation between each component and motion concern. Layout draft is used to realize notional design in SolidWorks, build file of general assembly graph above all, the scale in assembling a document one or more draft, indicate the position of every component with draft, with " piece " the dimension that defines a spare parts and appearance, procrastinate move a spare parts to check the athletic concern between component. The layout draft that notional design phase forms is the base that undertakes plan discussion and group are designed in coordination. If changed layout draft,design of use layout draft assembles the gain with the biggest put oneself in another's position is, assemble body and its spare parts to be met update automatically subsequently, achieve a change to be in can apace is finished revise. (2) the task of structural design phase has two, it is to be motion to emulate analysis and structure firstly finite yuan the analysis provides a model, the detail that always wants oversight in the analysis (like alveolus, pour horn to wait) all should not be appear; It is to offer to be able to attend secondly enrol the primary reason that bid to devise plan, enrol the need in bidding to convey clearly content should be clear that the earth's surface is amounted to, and negligible detail all omits. (3) the task of detailed design phase is expression and product are machined and assemble each detail that concern clearly. If spare parts model pours aperture of horn, bolt, pin aperture mediumly, the fastener in assembly drawing, standard component. 2.

The heavy-duty machine that is based on SolidWorks designs circuit with this correspondence, decompose products plan process for 5 phase. The task of the design technological process that fights the design of round of reclaimer to be a discussion ideal with brachial type, each phase reachs personnel duty. (1) the task of functional design phase is a basis the geographical environment of the user, carry requirement, fight the configuration of turbine and main function module certainly. (2) notional design is finished by project controller, undertake to the product module differentiates above all, deciding each function module is to use standard module, still pass right already some module add new configuration to undertake is out of shape designing, still undertake new design, use layout draft to determine the impact between each function component next, the key is to decide each motion joins the position between deputy positional coordinate or each kinematic pair affects dimension. (3) structural design is finished in coordination by 6-10 person commonly, be in charge of 1-2 each the design of functional module, every function module regards an independent assembly as body. Every member undertakes draft of total position of basis of controller of derive design, project undertake to each function module general assembly is designed for the foundation with total position draft. (4) the hands industrial stylist to have a product as a result beautification design that the structure designs, deliver emulation analysis engineer to undertake structural intensity is analysed athletic emulation mixing, structural design, industry design, emulation analysis 3 person between ceaselessly iteration, make the structure of the product tends perfect. (5) detailed design undertakes again after the result that the structure designs is decided, give a project to pursue. 3, products plan is politic 1.

Design and configuration of the product in production process are in design and in making, different level often needs different product model, the configuration function of SolidWorks solved this problem effectively. Found spare parts and when assembling system, the model can generate configuration of a default automatically, below normal circumstance, configuration of a default can satisfy a requirement. But a few special spare partses, what use an end according to the model is different, the likelihood needs to add many configuration. A few commonly used configuration are below. (1) default configuration is spare parts and the basic configuration that assemble system, when doing not have special requirement, the model has configuration of a default only normally. When the model has many configuration, default configures the result that is used at saving detailed design commonly. (2) assembling configuration is to come true to assemble the configuration that body builds a model and adds greatly, to reduce the memory of the model to measure, assembled configuration to compress all with the feature that assembles relation expression to have nothing to do. (3) structural configuration is to be used at motion to emulate the configuration that analysis and structural intensity analysis use, compressed all detail features that have nothing to do with the analysis. (4) project attempt configuration is the configuration that is used at giving a project to pursue, pursue medium in traditional 2 dimension project, the brushwork of some established by usage does not accord with umbriferous relation, give the brushwork of these established by usage for the picture, must do to the model a few revise, generate configuration of attempt of a project. (5) craft configuration is to describe the intermediate result of some working procedure in production process and the increasing configuration, semifinished product configuration that if use Yu Zhu,makes technology, craft configuration that to be being machined in CNC Machining working procedure the feature undertakes descriptive. 2.

Configuration design and parameter change design arm type to fight round of reclaimer, circle to be in charge of belt conveyer is a model is custom-built turn product, seriation product, products plan workload is very big, if can realize parameter to the set that turn is designed and configure a design, can improve design efficiency greatly. The parameter of SolidWorks changes design and configuration design function to satisfy this kind of requirement quite. Although SolidWorks is parameter,convert design software, but must plan reasonably the process building a model of component, ability realizes parameter effectively to change a design. When geometry builds a model, should assure, the model when the parameter of modification model won't make mistake; Need to change very few dimension to be able to realize the modification to the model only, and do not cause other feature change. Want to undertake parameter changes a design effectively, must undertake thorough analysis to the dimension of the model. It is dimension cent 4 kinds commonly: Functional dimension, structural intensity dimension, structural composition measure and associated dimension. (1) functional dimension is the size that determines according to product functional requirement, when designing series product, take to functional dimension a series of value, make the series of the product. When optimizing a design, functional dimension is not changed commonly. (2) the dimension that structural intensity dimension is reflective component intensity, the value of intensity dimension decided the security of the product, its value is greater, the product is safer, cost is higher also. To balance the contradiction of safety and cost, often take different cost to structural intensity dimension, use finite the method of yuan of analysis undertakes much program contrast optimize, decide its are optimal value. (3) structural composition measure decides a part or the feature concerns in the position in product model. The value of structural dimension also will make the series of the product. (4) the dimension correspondence between feature of associated dimension description concerns, decide according to the series value of functional dimension commonly. Undertake classified facilitating understanding the concern between dimension to dimension, affirmatory parameter changes the active dimension when the design and driven size, so that propose model and measure correctly,tag. In SolidWorks software, the seriation design of the spare parts comes true commonly through inserting EXCEL to express, also can come true through adding new configuration. The process that component seriation designs is to add new configuration first commonly, appoint different spare parts configuration to should configure every medium spare parts again, form range of products. Besides can undertake configuration to dimension, OK still wait to define attribute to undertake configuration oneself to the material of the spare parts, manufacturer home, form rich range of products. 3.

Structural member designs the spare parts that through soldering craft joins together to call structural member. Structural member has 3 kinds of processing techniques. To the structural member that solder by profile and becomes, solidWorks offerred a very good welder to provide -- solder feature. Use connect cuts out, horn is maintained board, the welder such as topmost lid is provided can efficient the ground undertakes structural member is designed, after the design is finished can make cut detailed list automatically. There is substantial profile library in SolidWorks, of profile sectional also can define oneself. Insert solder after the feature, the system can generate two acquiescent configuration automatically: Configuration of a father is " press treatment " , configuration of a derive is " by solder " , describe respectively solder the condition after condition and machine are machined, be not the structural member that profile solders to waiting with board makings, hypostatic spare parts, use much substance to build a model to go to the lavatory quite commonly, such assembly in SolidWorks in body, structural member when the spare parts is not child assembly parts will handle. But if a certain component in structural member is Ban gold, want to decide next makings develop a plan, because much substance builds a model not to support Ban gold, must use assemble body to design structural member. 4.

Assemble the design method that devises politic general assembly to use from bottom to top commonly. Be confined to is current the speed of the computer, right large the design that assembles body to undertake from above to below is not actual still. The design strategy of general assembly is with notional design phase finished layout draft is a basis, insert child assemble system. Child assemble should choose from bottom to top and method of design of from above to below reasonably. To brand-new design the proposal uses the design method of from above to below, can realize associated sex design so. If need to cite to already had component or standard component, answer union of two kinds of methods is used, build layout draft above all, insert modular component and spare parts for the foundation with layout draft, to the spare parts of new design, assembling an environment next deciding that its appearance, size reachs the place in assembling system. The advantage of method of design of from above to below is when the design is changed, relevant spare parts establishs the foundation the method and update automatically. To emblem mark with general part, the design had better fall in part pattern, and assembling the design that from above to below uses below the environment, in order to maintain the versatility of the spare parts. The component of heavy-duty machine is very much, be in commonly above of 10000 spare partses. SolidWorks offerred those who abound to assemble a function, can have agile combination to the spare parts, form child assemble or standard module. The method that SolidWorks processing assembles greatly is right the spare parts undertakes be changinged gently, the user can appoint a threshold values, exceed threshold values when the spare parts amount that assembles system, enter assemble mode greatly, undertake automatically be changinged gently to the spare parts. Implementing another strategy that assembles greatly is right component is built assemble configuration, compress all with the feature that assembles a relation to have nothing to do. 4, products plan and the core technology that the compositive and heavy-duty machine that the project analyses designs are structural intensity analysis. Finite yuan analytic tool can be divided it is two kinds, those who face design process, the main trend that uses for the engineer analyses software; Be used at undertaking to designing a result desired result is analysed, the major that uses for professional analyses software. The mode that Hua Tai weighs labour to create limited company is all designs software of COSMOSWorks of tool of analysis of personnel control mainstream, the structural intensity analysis of product component class comes true in designing a process; Establish professional emulation lab, deploy 5 major to analyse personnel, the systematic level that uses major to analyse software to have a product is analysed and the foundation studies theoretically. 1.

Facing the analytic COSMOSWorks that designs a process is a plug-in unit of SolidWorks software, share unified database with SolidWorks, product model data agrees completely, operation interface is unified, it is the structural analysis software with a complete function. Use COSMOSWorks undertakes structural analysis has below 3 clear advantages: (1) after undertaking modification to CAD model, analytic process (include reseau to differentiate, load definition, attrib border condition) do not need redefine, need to move only " analysis " command, the program can is opposite the product model after revising undertakes an analysis afresh, convenient and quick. (2) when having much program trade off study to the product, every kinds of plan can is to build a configuration below CAD environment, need to configure the definition that has analytic a process to only below analytic environment, when to other configuration undertakes an analysis, need to carry out only " procrastinate, pull " operation, the analysis that has defined process copy arrives below new configuration can, OK and special implement much plan conveniently compare a design. (3) when undertaking product measure optimizes a design in COSMOSWorks, solidWorks builds corresponding configuration for combination of each groups of dimension, when the optimal value that chooses to optimize a result when the user or some group dimension are combined, do not need to build a model afresh, need to choose corresponding configuration in SolidWorks only, got the product model of need. These advantages make the product optimizes a design to become very convenient, improved the design quality of the product greatly. 2.

Design model and the unity that analyse a model accomplish design model and the unity that analyse a model, will rise greatly finite yuan of analytic efficiency. Can pass below 3 kinds of methods come true: (1) to all designs personnel undertakes finite of yuan of analysis knowledge groom, understanding is limited yuan of analysis model and product are detailed the distinction of the model, requirement design personnel considers when products plan finite yuan of analysis requirement, the structure that is used at analysing configuration to needing analytic component to build is configured. (2) from proceed with of products plan flow, build design phase of a structure, aggrandizement designs the understanding of personnel bisect analyse. Just enter detailed design and project attempt scale through approbated model only, can reduce invalid labor. (3) deliver CAD model to major to analyse software when need (like NASTRAN, ANSYS) when, the much more hypostatic technology that hypostatic unit suggests to use SolidWorks builds a model, it is OK to such is in in analytic software very the size of mesh opening that differs to different diagnostic set conveniently. Housing unit had better use the technology of curved surface modelling of SolidWorks to build a model, such can better the unity that assures housing unit and product model. 5, after applied effect uses SolidWorks software, hua Tai is versed in the product of production limited company developed a level to jump a new chance to extricateoneself from an awkward position again. Main show is in 3 respects: (1) came true not to have accident design, assemble a problem the most crucially in the spare parts of SolidWorks is changed gently and configuring a design to solve three-dimensional applying greatly, realized the fictitious design of complex product, basically eliminated the elementary error of products plan through interfering an examination, the client's feedback is better and better also. (2) rose to design efficiency, the configuration design of SolidWorks satisfied seriation design and custom-built the requirement that changes a design, cooperate the use of diagnostic library, spare parts library, component library, raised the durability of the design. Realized a group to be designed in coordination through layout draft and derive design, group cooperation is closer. (3) rose to design quality, COSMOSWorks Yi Xueyi is used, can have much plan conveniently in designing a process compare a design, cast off traditional experience design and analogy design, came true to be based on an analysis optimize a design.
