摘要

针对约束层阻尼短圆柱壳拓扑优化问题，采用基于模态应变能法的渐进结构优化算法（ESO），引入独立网格滤波技术，通过灵敏度分析，用ANSYS的参数化设计语言APDL编写拓扑优化程序，获得一定约束层阻尼材料用量的约束层阻尼最优拓扑构形，并对约束层阻尼材料的优化布局进行实验验证。研究表明该拓扑优化方法正确，用于短圆柱壳约束层阻尼材料布局优化具有较强的工程实用性。

Abstract

This paper considers the use of Evolutionary Structural Optimization (ESO) algorithm in conjunction with modal strain energy method to solve the topological optimization problem for short cylindrical shell with constrained layer damping treatments. Furthermore, the independent grid filtering technique was used to obtain a regular optimized constrained layer damping layout. The topology optimization procedures was performed by using ansys parameter design language(APDL). The optimal topology layout of constrained layer damping was obtained for the short cylindrical shell with constrained damping layer treatment under the constraint of damping material consumption. Finally, theoretical results are verified by experimental study on the short cylindrical shell with optimal topology layout of constrained layer damping treatment. Results show the effectiveness and feasibility of the proposed topology optimization method. A potential application in the layout optimization of constrained layer damping for engineering structures is thus demonstrated.
