讨论了可变阻抗滑动轴承动力系数的试验测试和识别方法，滑动轴承的动力系数不是可以直接测得的物理量，它们只能从测得的转子—轴承系统的动态响应函数中采用参数识别的方法求得．本文首先描述了用于测试的试验装置的组成和测试程序，然后讨论了从测得的系统频率响应函数中识别动力系数的模态分析方法，最后讨论了测试结果．文中的结果证实了可变阻抗滑动轴承动态特性的可调性能．
The test and identification methods of variable coefficient sliding bearing dynamic coefficient are discussed. The dynamic coefficient of sliding bearing is not directly measurable physical quantity. They can only adopt parameter identification method from the measured dynamic response function of rotor-bearing system Obtained. This article first describes the composition and test procedure of the test setup used for the test, then discusses modal analysis methods that identify the dynamic coefficients from the measured system frequency response functions, and finally discusses the test results. The results in this paper confirm the adjustable performance of the variable impedance sliding bearing dynamic characteristics.
