|
The key step in flashless forging is to optimize the design of preform die shape.This paper uses a new optimization approach named micro genetic algorithm to optimize the preform die shape in H\|shape axisymmetric forgings.The object is to achieve flashless forging and complete filling.The result is satisfactory and the approach is approved to be effective.Moreover,with this approach the numerical simulation result can be easily used to guide the design optimization,and the bidirectional integration of CAD/CAE is accomplished.
