摘要
针对复杂的转子－轴承系统，提出了转子－轴承系统结构动力修改的灵敏度方法，以解决满足转子系统固有频率等设计要求的结构动力特性再设计问题。推导了非对称系统的特征灵敏度公式，并采用奇异值分解法求解结构参数修改量．
A new method of structural dynamic modification of complex rotor-bearing system by means of sensitivity analysis is proposed. This method is used to solving redesignproblem of the structural dynamic characteristic to meet the needs for specificeigenfrequeney. A formula of eigenralue of sensitivity for asymmetric systems is developed.The corrections of structural parameters are also obtained using the method SVD.
