Heuristic algorithm for topology optimization of continuum structure

Abstract

With the continuous development of science and technology, people have put forward higher requirements for the use of engineering structures, and how to optimize the design of structures better on the basis of satisfying constraints has always been the goal pursued by the engineering community. This paper studies the heuristic algorithm for topology optimization of continuum structures. The optimization calculation starts with a simple design area, and the deletion and addition of elements are considered at the same time in the iteration process. The new elements are grown around the elements with high stress and the elements with low stress values are deleted at the same time, thus the self-growth and self-evolution of structures can be realized. The simulation experiments show that the heuristic evolutionary method proposed in this paper is equipped with the ability to obtain the optimal topology of the structure, thus proving the accuracy and effectiveness of the proposed method.
