It is often difficult to suppress vibration of flexible rotors at high-order critical speeds through conventional low-speed balancing, especially in the case of the rotor with initial bending. In this paper, a low-speed dynamic balancing method for flexible rotors with initial bending is presented first. Combining the modal information of the rotor with the measurement data at speeds below the critical speeds, the low-speed dynamic balancing method is able to balancing the critical speeds without directly measuring the vibrations at the critical speeds and the initial bending of the rotor. Based on this, a mode-by-mode forward higher-order-extra-trial-weight-free method is proposed for balancing the higher modes simultaneously. In the proposed method, the lower-mode balancing weights on different balancing planes are used as trial weights and linked by the modal ratios of the measuring points. This avoids the potential severe vibration when pass through the critical speeds if any additional trial weights are used for balancing the higher-order modes. The proposed method is validated by numerical simulation and experimental tests respectively. The results show that the proposed method is better than the traditional influence coefficient method in balancing performance. In addition, it also avoids potentially high resonant vibration response, thus providing a safer approach for the high order dynamic balancing of flexible rotors.

在常规的低速平衡后,往往很难抑制柔性转子在高阶临界转速处的振动,尤其是存在初始弯曲的情况。本文介绍了一种针对初始弯曲柔性转子的低速动平衡方法,在不直接测量转子初始弯曲的情况下,结合转子的模态信息与低于临界转速下的测量与平衡数据,来估计抑制临界转速振动(包括初始弯曲和不平衡引起的)所需的不平衡校准量;在此基础上,针对高阶模态的平衡,提出了一种逐阶向前平衡的高阶无附加试重法,即利用不同平衡面上的低阶平衡配重作为试重,并结合测点模态比建立联系,从而避免了平衡高阶模态时因附加试重而破坏低阶临界转速的平衡。通过数值仿真和试验对所提方法进行了验证,结果表明,相比于传统的影响系数法,所提方法在所关心的转速域内有更好的振动抑制效果,且在保证平衡效果的同时避免了平衡测试过程中出现显著共振,提高了测量的安全性,从而为柔性转子的动平衡提供一种思路。
