A New Evolutionary Optimization Method and Its Application to A Piston-Crank Mechanism

Abstract

In this paper, the authors present a new evolutionary optimization method for three-dimensional structural statics. The method consists of two optimization processes in series. The former process is to deal with the topology optimization. The latter process is to deal with the configuration optimization. The method finds an approximate optimum topology and configuration of the structures to be improved from any initial design of them. We show application of the method to a crank arm and a connecting rod as a fundamental verification.
