Abstract：With the method of pseudo-excitation，the cantilever double-disc rotor system under the bearing rotary random power incentive, the random rotor imbalance excitation and the random response of the ground stationary random seismic excitation are analyzed by computer numerical simulation . The results show that: It is a greater impact on the random response of bearings by bearing rotary stochastic dynamic incentive, but it is less affected to disc random response, so that the bearing stiffness should be controlled within a certain range. Cantilever disc and the random vibration of non-cantilever bearing should be paid more attention to.
