摘要
机组动静局部接触时会造成冲击力、摩擦力以及系统的刚度的改变,摩擦振动的特征表现为振幅大幅波动或迅速爬升,转轴扰度变化等,介绍了机组启停及带负荷中的碰磨情况,并以实例分析。
The static and dynamic partial contact of units can result in change of impact force,friction,and systemic rigidity.The features of frictional vibration manifested as sharp fluctuate or rapid increase of swing,change of shaft bending moment and so on.The touching and friction of units during start-stop course or with load are introduced,and relevant example is analyzed.
