| 摘 要： | 频响函数灵敏度是结构振动控制，破损诊断和动力优化中很有用的信息，然而，对频响函数灵敏度的研究还不多。基于动柔度混合幂级数，对于无阻尼频响函数灵敏度分析提供了一种可行的动柔度法，它是特征向量导数计算中的动柔度法移植后的结果。数值考核表明，这种方法的精度良好。

| Abstract: | The sensitivity analysis of frequency response function is a very useful information
in the fields of vibration control,damage detection and dynamic optimization of structure,
however, the investigation associated with it is rare. Based on a mixed power series of
dynamic flexibility, a feasible dynamic flexibility(DF) method for the sensitivity analysis of
undamped frequency response function is provided in this paper. The DF method is developed
in order to compute the eigenvector derivative. Numerical results show that the precision of this
method is good. |
