| 摘 要： | 本文提出利用模态参数识别技术进行挠性转子动平衡的方法。为了计及平衡过程中测试数据的误差,对动不平衡量采用极大似然估计。本文给出计算机模拟的几个实例以论证此种方法,并提出加速收敛的措施。计算结果表明此法效果是鸿意的。

| Abstract: | The present paper offers a method of balancing dynamically the flexible rotors with the technique of modal parameter identification. To take the errors of measurement data in the process of balancing into account, the maximum likelihood estimation is adopted. In order to demonstrate the validity of this method, some examples with computer analog are given and the measure to accelerate the convergency is proposed. The computation results show the effect of this method is highly satisfactory. |
