| 摘 要： | 研究了连续结构在外力作用下的声辐射拓扑优化问题。运用有限元法(FEM)分析结构响应,运用边界元法(BEM)处理外场的声辐射问题,采用渐进结构优化(ESO)来进行声拓扑优化分析。以一平板为例分析了在外谐力作用下的结构-声辐射拓扑优化。结果表明用渐进结构优化(ESO)来进行结构-声拓扑优化是可行的、有效的。

| Abstract: | The continuum structural-acoustic topology optimization under external loading is investigated herein. Finite Element Method (FEM) is used to obtain the structural frequency response and Boundary Element Method (BEM) is adopted to perform exterior acoustic radiation analysis. The Evolutionary Structural Optimization (ESO) is served as an optimization method in structural-acoustic radiation topology analysis. The acoustic radiation optimization of a plate under harmonic excitation is given for example. The numerical results show that using ESO solution to analyze structural-acoustic topology optimization is feasible and effective. |
