简谐力激励下约束阻尼结构动力学拓扑优化
Dynamic Topology Optimization of Constrained Layer Damping Structure under Harmonic Force Excitation
摘要
Abstract
For harmonic force excitation, dynamic topology optimization of constrained layer damping (CLD) structure is studied. Considering the displacement amplitude at the specified location of CLD structure as the optimization objective and the consumption of CLD material as constrained conditions, the topology optimization model of CLD structure is developed. The displacement response of CLD structure is solved by the complex mode superposition method. Through analyzing the characteristics of the direct method and the adjoint method, the combination of the complex mode superposition method and the adjoint method is proposed to improve the efficiency of sensitivity analysis. The topology optimization model is solved by Method of Moving Asymptotes (MMA).The theoretical results show the effectiveness of the proposed optimization method.关键词
