| 摘 要： | 推导了多自由度正交阻尼结构的摄动重分析方法，计算在位形空间中进行，适用于原结构有重特征值的一般情形，全部计算只需待摄特征对信息，且“弹性”柔度与设计参数ε的变化无关，从而提高了计算效率。

| Abstract: | n this paper the authors develop a structural reanalysis procedure for multiDOF system with orthogonal damping. The procedure is executed in the configuration space. The present method can deal with the general case in which the original system has repeated eigenvalues. DUring computation only the real modes to be perturbed are of concern and the elastic flexibility is independent of the design parameter,thereby the efficiency of the mothod is enhanced. |
