摘要
在设定材料性能特性、几何尺寸、所受载荷为随机变量的情况下,CG随机有限元被用于结构振动分析。提出了基于随机有限元的结构振动优化设计方法。给出了一个计算实例,对计算结果做了比较,结果表明:本文提出的方法是有效的。
The material properties, geometry parameters and applied loads are assumed to be stochastic; CG stochastic finite element method is adopted to analyze the structure. The optimal design of structural vibration based on CG stochastic finite element is presented. An example is given respectively and the calculated results are compared to validate the proposed methods.
