Abstract

This article aim at solving the problem of local optimal solution easily appear in structural optimization by the algorithm of bi-directional evolutionary structural optimization (BESO), and importing improved genetic algorithm (GA), put forward a new algorithm named bi-directional evolutionary structural optimization based on improved genetic algorithm (IGA-BESO). In study, it adopts the dual coding method to build the model of the structure, through a suitable for topology optimization of crossover and mutation with penalty factor method to update the individual genes of the population. This paper, optimize a typical structure for compliance optimization with multiple load cases with method of IGA-BESO, and the optimization results show that the proposed method not only improves the computational efficiency, but also improve the stiffness of the structure.
