Investigation of a Practical Method of Structural Optimization by Genetic algorithms (Proposal of a Hybrid Ga and application towards the Thickness optimization of a CRT)

摘要

A new hybrid genetic algorithm (GA) and a parallel genetic algorithm are proposed in this paper in order to improve the convergence of structural optimization. The fully stressed design, FSD, method and a GA were incorporated into the hybrid GA. In the parallel GA, the "island model" was applied to reduce the computation ime. Stress analyses were carried out with a commercial FEM code to obtain the optimum Solution with high reliability even in a complex model.
