| 摘 要： | 采用结构模态振型来定义结构的形状优化参数模型,以一组结构模态振型的叠加来重构结构表面形状,以结构振动响应为目标函数,采用遗传算法优化配置各阶模态振型的参与因子来优化结构形状,以达到降低结构振动响应水平的目的.以几何平板、半圆柱曲面为研究对象,计算结果表明该方法可以有效降低结构振动响应水平.

| Abstract: | The optimization parameter model is defined by using the mode shape,and the targeted structure surface is restructured with a series of mode shape superposition.By choosing the vibration response as design function,the mode shape participation factor is distributed by using of genetic algorithm to get the optimized surface shape with smallest vibration characteristics.Some examples are demonstrated to verify the efficiency and accuracy of the method to reduce vibration response. |
