一、问题的提出作者在《水电机组盘车摆度特性的研究》一文里已经论证了:只要测得轴颈圆上互成90°位置的四个标定盘车点的摆度值,就可准确地算出该轴颈圆上最大摆度点所在的方位角及其摆度值。在水电机组的安装和检修实践中,盘车有各种方法:人力盘车、机械盘车、电动盘车、水力盘车等,各 First, the problem raised Author in the “hydropower unit crank swing characteristics of” a text has been demonstrated: as long as the measured circle round each other 90 ° position of the four calibration disc swing point value, you can Accurately calculate the journal axis of the maximum swing point where the azimuth and its swing value. In the hydropower installation and maintenance practices, there are a variety of methods of turning a car: human power car, mechanical car, electric car, hydraulic car and so on, each
