本文将区间模糊有限元法用于参数不确定结构的特征值和频响函数分析。为了减少区间分析和模糊分析的计算时间，将这些非概率方法与模态综合技术相结合。特别注意这种子结构技术的数学描述上的不确定性的影响。所有的概念都通过一个基准结构的例子来说明。
This paper uses the interval and fuzzy finite element method for the eigenvalue and frequency response function analysis of structures with uncertain parameters. In order to reduce the calculation time of the interval and fuzzy analyses, these non-probabilistic methods are combined with the component mode synthesis technique. Special attention is paid to the effect of uncertainties on the mathematical description of this substructuring technique. All concepts are illustrated through a benchmark structure example.
