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.
