Vibration Reduction and Optimization for Constrained Damping Plates based on Adding Material Evolutionary Method

  • 摘要: 研究阻尼结构的阻尼材料最优布局问题。基于虚功原理,构建约束阻尼板振动微分方程,从约束阻尼板若干基本假设出发,并根据阻尼板自由振动微分方程,推导了结构模态阻尼比表达式。建立了以阻尼单元相对密度为拓扑设计变量,模态阻尼比最大为优化目标,阻尼材料用量为约束的阻尼结构拓扑优化数学模型。以阻尼单元模态阻尼比敏度为寻优方向的依据,采用增材式渐进法(AESO)求解优化模型,并依据拓扑优化准则在结构上不断敷设阻尼材料。编程实现了AESO优化算法,仿真计算表明:采用AESO优化时,阻尼材料主要敷设于结构的模态应变较大位置,且不会产生棋盘格现象,并且优化后的结构一阶模态阻尼比较优化前可增加83.6%,而常规渐进法带来的增幅仅72.13%。为进一步验证优化效果,还对结构进行了谐响应分析,结果表明采用增材式渐进法优化时,结构可获得更佳减振效果。
