摘要
提出一种基于不平衡响应的滑动轴承油膜参数识别的最小二乘算法 ,建立了识别模型 ,进行了实验识别 .结果表明该方法能有效的抑制测量误差 ,提高参数识别精度 .
Based on unbalance response of rotor, a least-square method for identifying the dynamic characteristics of journal bearings is presneted. An identifying model is put forward. The experiment results show that the presented method is valid in reducingthe influence of measurement error on identifying precision and improving the precision of identification.
