摘要
在对边值模糊分析方法和优化边值模糊分析方法研究的基础上,将拉丁超立方抽样和响应面方法引入结构模糊分析,提出一种基于拉丁超立方抽样及响应面的模糊分析方法。讨论这种方法的数学运算,并与Monte Carlo方法进行比较。最后基于这种方法,对一个用隐式方程描述的有限元悬臂梁模型进行模糊分析,得到变形模糊结果。
On the base of Latin hypercube sampling and response surface method a method of fuzzy analysis of structures is presented.This method is based upon the vertex method and optimized vertex method.This methodology is studied and compared to Monte Carlo simulation.As a result,the method is illustrated by way of example.The example is a complex cantilever beam using finite element method having implicit functions.And the fuzzy result of deflection is calculated.
