| 摘 要： | 在形状优化中,传统的优化方法对目标函数和约束条件形态的要求严格,难以获得全局最优解。为解决这个问题,将微观遗传算法应用于结构形状优化中。既消除了对目标函数和约束条件形态的限制,提高了全局寻优能力;又减少了结构分析次数,节省了计算时间,为结构的形状优化提供了一种实用方法。通过算例,验证了该方法的正确性。

| Abstract: | In the shape optimization,the traditional optimization method has strict limit to the goal function and the restriction condition,and the overall optimum result can hardly be obtained.To solve this problem,the micro genetic algorithm is applied to the shape optimization of structures.The limit to the goal function and the restriction condition is then eliminated,and the ability of the algorithm for the overall optimization is improved.The time for calculation of the structure analysis is also reduced.A practical approach can be provided for the shape optimization of structures.The method is proved valid through the example. |
