摘要:
针对约束阻尼结构的动力学拓扑优化问题,基于实体各向同性材料惩罚模型(SIMP插值模型),以约束阻尼结构位移响应最小化为优化目标,约束阻尼材料使用量为约束条件,建立了约束阻尼结构位移响应拓扑优化模型.在位移响应的灵敏度分析时,将模态阻尼比的灵敏度引入到优化目标的灵敏度分析中,使优化目标的灵敏度计算更加准确合理.采用移动渐近线法(MMA)对拓扑优化模型进行求解.通过算例分析,验证了提出的约束阻尼结构的动力学优化算法的正确性和有效性.
Abstract:
The Solid Isotropic Material with Penalization (SIMP) was applied to establish the topology optimization model of constrained layer damping (CLD) structure.The minimum of displacement response was considered as the objective function and the volume fraction of constrained layer damping material as constrained conditions.The sensitivity of modal damping ratio was introduced in the sensitivity analysis of the objective function,making the sensitivity more accurate and sensible.The topology optimization model was solved by Method of Moving Asymptotes (MMA).The numerical examples demonstrated that the proposed dynamics optimization of CLD structure was of validity and effectiveness.
