摘要
讨论理论分析大不平衡非线性振动响应的局限性,指出大不平衡总是伴随着动静碰摩的发生。通过分析现场实测数据,总结大不平衡非线性振动响应特点。
Limitation of large unbalance nonlinear vibration numerical calculation answer is discussed. Field experience pinpoints that rotor-to-stator rub is always induced by large unbalance. Field measured vibration data analysis and large unbalance vibration response characteristic are also presented.
