| 摘 要： | 应用模态分析技术及向量原理，推导出转子－轴承系统特征值对设计参数的灵敏度公式．利用广义逆迭代法直接求解二次特征值问题，从而完全避免了２Ｎ维特征向量的规范正交过程．并对实际转子－轴承系统进行了计算分析．

| Abstract: | Based on model analysis technique and vector principle, this paper gives the sensitivity analysis formulas of the eigenvalue of rotor bearing systems with the change of design parameters. Generalized inversion iteration method is applied in the direct solution of quadratic eigenvalue, thus avoiding the normalization and perpendicularity of 2N dimensional eigenvector. A practical example of rotor bearing system is calculated and analyzed. |
