Optimisation of Forging Process Parameters using Genetic Algorithms

摘要

This paper presents an optimisation method for metal forming processes, especially for forging process designs, using a finite element thermal-mechanical analysis coupled with a genetic algorithm. The optimisation method has been developed for shape design of multi-stage forming processes. The shape design objective is to optimise the process parameters in order to make the achieved final forging product to approach the desired one as much as possible. Demonstrating the computational efficiency of the method a two-stage hot forging of an axisymmetric H-shape product example is presented.
