Study On Rapid Response Design & Optimization Of Forging Machine Products Based On CAD/CAE Compound Templates

Along with the division of market demand and the buyer's market coming into being, the consumers' demands such as multiplicity,diversity and individuation are getting considerably important.Some consumers started to customize the product.Therefore, how to improve the customized producing through distinctive rapid response design while reduce cost and response time has become a key emphasis.Firstly in the present article,the author analyzes the problems the forging machine enterprises facing,and points out the deficiency of the present design and optimization. Then the author proposes the key problem to solve'and the significance of the research.According to the problem of unconsolidated design and optimization process,the author tries to establish a compound CAD/CAE forging machine parts templates library, in order to apply the efficient parameter methods to both CAD model design and finite element analysis(FEA).By that,the regenerated CAD model and the CAE analysis result can be obtained rightly after parameters regulation.Finally,the author proposes a compound templates library based rapid design and optimization method architecture,which includes both CAD and CAE templates of forging machine parts.Subsequently,the paper presents the abstraction and abbreviation principle of feature based FEA model,and formulates the process from CAD model to CAE model by Pro/Engineer system.Then taking honeycomb-like beam as example,discusses the establishment of APDL parameter FEA model.Finally,the author uses XML to describe a APDL based FEA template,and defines the preparation and posttreatment process by XSD,by that,we establish a solid foundation to fast create FEA model combining custom requirements.As a case of compound CAD/CAE forging machine parts templates based rapid design and optimization method,the author proposes a new product design type-custom requirements driven forging machine rapid design system.The system starts from custom requirements to obtain the design goal,and applies DSM to coordinate the design tasks.By templates matching,the author extracts the CAD template from compound templates library,then obtains the design parameter by design knowledge.Based on Pro/Engineer platform,a detailed solution of several key technologies used in this system is provided.At the end,a successful application of this new design system is introduced.Following the compound templates library,the author sets up a FEA model generation method merged with custom requirements.Firstly,the paper sequentially formulates the dataflow of the modeling process,the determination of FEA feature and the method of extracting templates.Then,the author introduces a kind of data exchange method between CAD/CAE system and the representation of CAD/CAE model by XML.Finally,the paper sets forth the realization of forging machine rapid design and optimization system.At last,the author attempts tóapply the honeycomb-like structure to forging machine's beam structure optimal design.To solve the problem of optimization divergence, the author uses a kind of hybrid genetic algorithm based on dynamic searching method to stochastic optimization,and the result indicates the efficiency of the algorithm.As a part,this task is sponsored by the Chinese National Programs for High Technology Research and Development(No.2007AA04Z1A2).
