| 摘要: |
| 推导了基于瞬态加速启动响应信息的高速柔性转子瞬态动平衡方法，对涡轴发动机动力涡轮转子进行了仿真平衡。为考察在转速扰动、噪声等因素干扰下方法的鲁棒性，分别对2种情况下的平衡精度进行了系统的研究。研究结果表明，所建立的瞬态动平衡方法能对动力涡轮转子进行很好的平衡。扰动因素对平衡效率有一定的影响，会导致等效不平衡量识别精度下降，但整体仍具有很好的鲁棒性，可适用于大多数情况下的工程转子动平衡。 |

| Abstract: |
| A novel transient high-speed flexible rotor balancing method is derived and the transient run-up response information based balance method is used to balance a power turbine rotor of turboshaft engine. The balance efficiency is studied systematically to prove its robustness under two disturbance factors, i.e., random disturbed rotating speed and noise polluted vibration signal. Results show that the transient balance method can achieve satisfactory balance efficiency on real rotors. The disturbances have influence on the identification accuracy of the equivalent unbalance, but the robustness is good on most cases and it is a suitable technology for real applications. |
