Research on Optimization Algorithm of Bidirectional Evolutionary Structure Based on Stiffness Optimization

In this paper, a new design idea is proposed for the realization of bidirectional evolutionary structural optimization (BESO) method. First of all, this paper introduces the realization of bidirectional incremental structure optimization design, and gives a detailed optimization process, analyzes the theoretical model of the actual engineering problem under static load and multi-conditions, and puts forward the method of stiffness topology optimization. Secondly, in order to obtain the maximum stiffness, a bidirectional evolutionary structural optimization method is adopted and the optimal topology is finally obtained through multiple iterations. On this basis, the topology optimization of complex two-dimensional and three-dimensional structures is realized by the secondary development of bidirectional evolutionary structural optimization and computer software. Finally, three elements of engineering applications covering different factors and working conditions are given in this paper. It is proved that the theory can get better theoretical results than traditional optimization methods, and the Maneuverability and flexibility are better. In practical engineering applications the theory also has a guiding role. The optimization ideas provided in this paper enriches the way of topology optimization to a certain extent.
