| 摘 要： | 提出一种可用于大型滑动轴承油膜动特性系数在线识别的新方法。该方法利用高速动平衡机特殊的支撑结构，通过改变运动中转子一滑动轴承的支撑刚度，拾取刚度改变前后系统动不平衡响应的稳态值，来确定油膜动特性系数。实验结果表明，该方法具有较高的精度和可靠性。

| Abstract: | A new method for on-line identifying oil film dynamic coefficient of large journal bear-ing is proposed. The method utilizes the special supporting structure of the high speed dynamicbalancing machine. The dynamic coefficient of oil film is determined through changing the sup-porting stiffness of the rotor-journal bearing system in motion, picking up the unbalance stableresponse of the rotor-journal bearing system before and after the stiffness change. Experimentalresults show that the method is of high precision and reliability. |
