摘要
在对结构动力学进行研究时,为了提高结构设计的可靠性,需考虑结构参数的模糊性。目前工程上的动力学分析往往是基于确定性的研究,这会使得分析结果与实际情况存在着差异,且目前没有专门通用软件来求解含有模糊参数的结构动力学问题,为此本文基于泰勒展开法,运用Patran的二次开发功能,编写PCl函数,建立Patran-Nastran下的结构动力学模糊求解模块,解决在结构设计中遇到的参数模糊性问题。
With the further researches on the engineering problems,the reliability of the structure is higher requested.Recently,most of researches on the structure mechanics are based on the deterministic analysis,while the parameters of the structure are usually uncertain,which may lead the responses uncertain.Currently,There is no specialized analysesoftware of structure mechanicsto solve the structure problems with fuzzy parameters,With the help of the secondary development functions of Patran-Nastran,the model of solving the fuzzy structure mechanicsunder Patran-Nastran is built byusing Taylor expansion to solve the fuzzy problems which wasencountered in Engineering.
