| Abstract: | The simulative design method which optimizes metal plastic working by means of the simulation technique of UBET according to metal plastic forming theory is presented,the simulation technique of UBET and the basic method of optimal design are described and the CAS/CAD system which optimizes forging process and forging die parameters is established by the method.The simulative design solves the problems that one must test many times and the optimal design can not be done in empirical design.It is proven by the success in laboratory and factory practice that the simulative design method possesses a strong appeal and good application prospects. |
