In a hydrodynamic lubricated journal bearing supported rotor system, the oil-film stiffness and damping characteristics are very important to the prediction of vibration performance and to which turbo-generator set designers usually pay much attention. The procedure of experimental determination of such characteristics presented in the past was imperfect since the results obtained were rather dispersive. Many aspects which influence the accuracy of measurement have been investigated in the Bearing Research Group in Xian Jiaotong University. Several preliminary conclusions could be made now from the investigation, such as 1. When inverted test rig structure in designed, the inertia terms in the equations of motion play an important part in the force equilibrium and an amount of error will be brought in when they are neglected; 2. The axes of the test bearing and the shaft should be kept parallel as well as possible by the rig structure design; 3. The most important influence of the shaft deflection under load on measuring accuracy is due to the deflection difference at bearing middle and at the position the non-contact transducers are mounted therein, and a correction should be made carefully to the values measured by the tranducers; 4. The "noise" introduced due to inhomogeneity of magnetic and electric conductances at the rotating shaft surface when inductive and eddy current tranducers are used might be in a higher order comparing with the displacement signals; 5. The gain factors and phase factors of the frequency-response functions of an instrument system are different for different channels, therefore a dynamic calibration procedure is necessary. The improvement made by the BRG concerning to and some of the results including data and curves are also introduced in the present work.

在流体动压滑动轴承支承转子系统中,油膜的刚度阻尼特性,对于予测振动是非常重要的,因而经常深受汽轮发电机组的设计师们的注意。然而过去发表的试验测定方法尚不完善,所得结果离散度很大。我们曾经研究了影响测量精度的多方面因素,并得到如下之初步结论:1.当设计的是倒置结构的试验台时,运动方程中的惯性项在力平衡中起相当作用,忽略这一项将产生一定的误差;2.所设计的试验台应尽可能保证试验轴承和轴的轴线平行;3.轴受载挠曲对测量精度最重要的影响是产生于轴承中点处和安装非接触式传感器处的挠度不一样,因而必须仔细地修正传感器的测得值;4.当使用电感式或电涡流式传感器时,由轴的旋转表面导电率和导磁率不均匀产生的噪声可能比位移信号大一个数量级;5.一个仪表系统各通道频率响应函数的增益因子和相位因子是不同的,因而需要采用动态标定措施。本文还介绍了我们的解决方法和结果数据。
