摘　　要：本发明公开了一种基于双向渐进优化算法的约束阻尼板的优化设计方法，属于结构优化设计技术领域。该方法包括：建立约束阻尼板的有限元模型；建立拓扑优化模型；设定双向渐进优化算法的参数；计算约束阻尼板结构单元的灵敏度；采用双向渐进优化算法逐步删除低效率约束阻尼胞单元，同时恢复灵敏度高的已被删除的约束阻尼胞单元；满足约束条件时停止迭代，输出约束阻尼材料的优化布局。本发明在一定约束阻尼材料用量的情况下，使约束阻尼板的模态损耗因子最大化，使约束阻尼板结构在有效减振的同时不过多附加质量。

主权项：一种基于双向渐进优化算法的约束阻尼板的优化设计方法，其特征在于，包括以下步骤：1)在待优化表面覆盖约束阻尼材料形成约束阻尼板结构，建立约束阻尼板结构的有限元模型，定义边界条件；2)建立拓扑优化模型如下： $\{\begin{matrix} find : x_{i}, i = 1,2 . . . n \\ \max : η = η_{r}, (r = 1,2,3, . . .) \\ s . t : V = Σ_{i = 1}^{n} x_{i} v_{i} \leq V^{关键词：法律状态：生效IPC专利分类号： G06F17/50;G06F17/00;G;G06;G06F;G06F17;G06F17/50;G06F17/00var ShareData = new Array();
