多学科设计优化, 多学科视图建模, 协同仿真, CAD/CAE集成技术

A multidisciplinary view-modeling technique for MDO of complex products was proposed and the master model-oriented multiple disciplines concurrent modeling technical routine was given. Through constructing the process model for multi-level decomposing and mapping of complex product design, the product composing nature of multiple disciplines was analyzed.A multidisciplinary concurrent design approach was

 put forward in order to achieve the independent function and minimum information of each discipline subsystem. The conflict problems of multidisciplinary view-models were solved by means of the consistency rules for modeling and collaborative running strategies. The multi-level application architecture of multidisciplinary view-modeling technique was established by the object-oriented programming method. Based on the integration of optimization technology and CAD/CAE technologies, collaborative simulation and optimization of multidisciplinary view-models can be realized certainly. Also, this technique was used in car-body modeling and simulation for multidisciplinary optimization, the dynamic interaction and multidisciplinary sharing of the design information really come true. The product design level is improved effectively and design efficiency is promoted greatly.
