蒙特卡罗数值模拟法在随机参数转子动力学响应中的应用

本文运用模拟量输出卡和功率放大器生成符合正态分布的随机电流，根据已有的支撑刚度和随机电流之间的线性关系，得出支撑刚度的均值和标准差。在已有的转子系统模型上，利用蒙特卡罗数值模拟方法对随机参数进行模拟计算，得出支撑刚度参数的改变对转子动力学响应位移的影响。

The application of Monte Carlo simulation to the stochastic parameter rotor dynamic response

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.
