一、前言随着水电机组单机容量的增长,对机组运行稳定性和可靠性的要求越来越高。为调整机组轴线和决定导轴承间隙,常以盘车参数作为计算根据。目前国内沿用的盘车摆度计算方法准确度并不高,即以“八点盘车法”求出的最大摆度点往往并不是真实的最大摆度点,其摆度值也往往小于真实的最大摆度值。本文试图首先对理论的盘车摆度特 I. Introduction With the growth of the stand-alone capacity of hydropower units, the requirements on the operation stability and reliability of the units are getting higher and higher. In order to adjust the axis of the unit and determine the guide bearing clearance, it is often calculated according to the crank parameters. At present, the calculation accuracy of the crankset used in China is not very high. That is, the maximum swing point calculated by the “eight-point crank method” is not always the true maximum swing point, and the swing value is often smaller than the real The maximum swing value. This article attempts to first articulate the theory of crankset
