在以往的静平衡试验中由于导轨与转轴间的摩擦,使试验产生误差。采用两次试加法,在每次试加时有意识地调整试加质量的大小,使转子产生明确的转动方向和转动趋势,进而应用力矩平衡原理将因导轨与转子间摩擦产生的误差消除。
In the past static balance test due to friction between the guide rail and the shaft, the test error. Adopt two try-and-add methods, consciously adjust the size of try-on mass during each trial, so that the rotor has a clear direction of rotation and rotation tendency, and then the principle of moment balance will eliminate the error caused by the friction between the guide rail and the rotor.
