摘要
以Ｈｉｌｂｅｒｔ空间为基础，建立了试验模态与计算模态相关性的度量，给出一种判断有限元计算与试验模态分析结果的可靠性的方法。并且以薄壁圆桶为对象进行了实际分析验证。
In this paper, the measure of correlativity between test modal and computational modal was established in Hilbert space. A method judging the reliability of finite element computation and test modal analysis was given. The method was verified by analyzing thin walled cylindrical shell practically.
