采用有限元法计算了预研核心机转子的支承结构静刚度,所得数据与地面台架试车结果比较吻合,说明方法正确,其结果可用以分析预研核心机转子支承系统的动力特征。
The static stiffness of the pre-engineered core rotor was calculated by using the finite element method. The obtained data are in good agreement with the test results of the ground platform, indicating that the method is correct. The results can be used to analyze the dynamic characteristics of the pre-engineered core rotor support system.
