By considering the characteristics of information generation of chemical industry product configuration model,a new method of constructing chemical equipment configuration model based on axiomatic design theory was presented.In this method,functional domain mapping into physical domain was introduced,functional requirements with constraints were defined as function constraint integrated component(FCIC),design parameters with feature were defined as structure feature integrated component(SFIC),and the configuration model based on SFIC was constructed by establishing database and the characteristic relationship of SFIC features.Axiomatic design made configuration modeling more scientific,and helped the designer decide more quickly and accurately.Finally,a case study of configuration design for air separation equipment was presented.
To illuminate the necessity of model evolvement and rouse,dynamics of injection molding machine' sproduct models are analyzed.The performance knowledge is used to support the model evolvement andreuse.The driven factors of mechanical product model are concluded.The dynamic characteristics ofproduct model are described.The.performance knowledge is used to improve specific evolvement process.The upper-layer passing rules are adopted in the mechanical product comfiguration design.The rules ofproduct model evolvement are investigated.And the model evolvement of injection molding machine hasthree levels.Practical and effective realization arithmetic is given to roalize the performance knowledgereuse.Finally,HT1800X1N series injection molding machines are taken as examples to illuminate thatthe arithmetic is correct and practical.
Aiming at the problem existing in the computer aided design process that how to express the design intents with high-level engineering terminologies,a mechanical product self-organized semantic feature evolution technology for axiomatic design is proposed, so that the constraint relations between mechanical parts could be expressed in a semantic form which is more suitable for designers.By describing the evolution rules for semantic constraint information,the abstract expression of design semantics in mechanical product evolution process is realized and the constraint relations between parts are mapped to the geometric level from the semantic level;With semantic feature relation graph,the abstract semantic description,the semantic relative structure and the semantic constraint information are linked together;And the methods of semantic feature self-organized evolution are classified.Finally,combining a design example of domestic high-speed elevator,how to apply the theory to practical product development is illustrated and this method and its validity is described and verified.According to the study results,the designers are able to represent the design intents at an edvanced semantic level in a more intuitional and natural way and the automation,recursion and visualization for mechanical product axiomatic design are also realized.
Product customization has been recognized as an effective means to implement mass cus-tomization (MC). A new theory and method for MC-oriented evolutionary design of configuration product is presented based on the study of developing law of evolutionary design in integrated envi-ronment, which focuses on the innovation and reuse properties of configuration product. The key technologies for general requirement modeling in quick response to customer requirement, multi-level stepwise configuration optimization driven by customer requirement and evolutionary deduction of product variable structure based on configuration association are thoroughly investigated. The suc-cessful application of the presented method in the development of real-life products demonstrates its utility, flexibility and robusticity.
