摘要 本文基于渐进结构拓扑优化方法,以阻尼结构的模态损耗因子最大化为目标,探讨了在阻尼结构设计中的阻尼材料最优分布问题,得到了在一定材料用量下的阻尼材料的最优分布构形,对于阻尼结构的轻量化设计有一定的意义。 Damping material optimal placement in damping structure design was studied. A mathematical model of the modal loss factor maximum was constructed, and the damping material optimal placement was found by evolutionary structural optimization(ESO), The method is suited for free damping structure and constrained damping structure, by using less material.
