| 7. | The method of adding an appropriate balancing mass on the rotor in the appropriate direction and location of the initial bow of the rotor shaft can be used to reduce the vibration of the double disk fault system effectively
分析和实验的结果表明，在转子弯曲故障的反方向以及轴上合适位置施加合适的平衡质量能有效地降低双盘弯曲故障转子的振动。 |
| 8. | For balancing the bow fault rotor , not only the quantity but also the balancing location of the balancing mass should be considered together to prevent the extra resonant caused by the balancing mass itself , for the initial bow mainly excites the first resonant amplitude
为了有效地平衡弯曲故障转子，施加平衡质量时不仅要考虑合适的质量大小，还要考虑平衡质量在轴上的位置，以防止激起系统的二阶共振。 |
