This article utilizes analog output (AO ) and high power amplifier to generate random current which fits to Normal Distribution , and come to the mean and standard deviation of the bracing stiffness on the basis of the linear relationship of the existing bracing stiffness and random current. Upon the rotor system model ,using Monte Carlo simulation to do the simulation calculation of random parameters, we conclude the influences of the change of the bracing stiffness on the rotor dynamic displacement.
