Abstract:

Along with the rapid development of computer technology, complex technology is often used to solve complex problems in the highend industrial technology, directly resulting in the rising cost of design. Aiming at the high cost of design and the present situation of the application of highend CAE technology that is affected by the competition of talent resources, we take the brake shoes design in vehicle braking system as an example, structure and layer the domain knowledge, and construct the knowledge base of active knowledge aided system by a mixed expression way that combines production rules with frame representation. We provide designers with lacked experience and knowledge rapidly through “active machinehuman knowledge aided system”, make designers be able to quickly make use of knowledge but not learn knowledge, realize the efficient utilization for design knowledge and experience, shorten the learning process of design personnel, lower the application threshold put by CAE, and finally reach the purpose of low starting application for highend CAE technology.

Key words: active knowledge aided system;knowledge base;CAE;brake shoe
