Numerical simulation technique has become the important verifying tools in extrusion and forging die shape design.It helps designers to know the design parameters space better.However,the vast computation cost,the implicity of object function and discontinuousness of search space limit the application of traditional gradient-based optimization methods.Some nongradient based optimization techniques,such as generic algorithm and simulated annealing usually need more simulation runs and become infeasible in a large scale simulation.In this paper,a hybrid intelligent optimization method based simulation knowledge is developed aiming at extrusion and forging process.The result of an extrusion-forging die shape optimization shows that this method is valid and feasible.
