1．根据转子系统运动方程简化支承，在I-deas里建立转子三维实体模型，定义材料参数、进行网格划分后，建立转子有限元模型，通过软件的模态分析和变量化分析模块，变量化轴承材料参数，等效支承刚度，优化有限元模型，并通过实验方法验证了模型的准确性。
2．对转子施加不平衡量，应用I-deas对失衡转子系统进行动响应频域分析，得到失衡转子系统振动特性，通过时域分析求解失衡转子在工作转速下的测点响应振型。
3．对时域分析响应振型应用相关滤波方法，在origin软件中使用FFT低通滤波，提取基频信号，得到不平衡量对应测点基频振幅和相位。
4．基于刚性转子的双面动平衡理论和影响系数法原理，根据动响应分析和基频分析数据应用Matlab程序求解影响系数法矩阵方程，最终得到失衡转子系统的失衡量大小。比较实验数据，得出该转子虚拟动平衡方法的可行性。
