基于遗传算法,引入无固定初始网格的载荷路径法对某机翼前缘进行拓扑结构优化,并对结果进行ANSYS仿真。在相同条件下使用初始网格固定的基结构法对同一问题进行拓扑结构优化。通过对两种方法优化所得的柔性结构变形结果进行对比分析,说明载荷路径法用于柔性机构拓扑优化的优势。 Based on the genetic algorithm, the load path method without fixed initial grid was introduced to optimize the topology of the leading edge of a wing, and the results were simulated by ANSYS. Under the same conditions, the initial mesh fixed structure method is used to optimize the topology of the same problem. By comparing and analyzing the deformation results of the flexible structure obtained by the two methods, the advantage of the load path method for the topological optimization of the flexible mechanism is illustrated.
