本文提出了一种利用柔性转子本身不平衡响应作为激励,利用小波变换理论去除嗓声,获取不平衡响应信号,识别油膜特性系数的新方法。实验结果评价表明,识别值具有较好的精度。
In this paper, we propose a new method that uses the unbalanced response of the flexible rotor itself as excitation, removes the noise by using the wavelet transform theory, obtains the unbalanced response signal, and identifies the oil film characteristic coefficient. Experimental results show that the identification value has good accuracy.
