摘要: 分析了裂纹轴转子系统在考虑涡动时的非线性动力学行为,并与忽略涡动时的裂纹轴进行了对比,发现二者在周期分岔特性、振幅特性、轴心轨迹和庞卡莱图等方面均存在明显差异。从而可以看出在考虑非线性涡动时,裂纹轴会出现复杂的动力学行为。所得结论对于早期发现和诊断裂纹故障有一定参考价值。

Abstract: Nonlinear dynamics of a cracked rotor with whirling were analyzed and were compared to a rotor without whirling.Distinct differences have been found in bifurcation,amplitude,orbit and Poincare map when carrying on this comparison.Complicated dynamics may be found when a cracked rotor has its whirling speed.The results revealed may be useful in crack-early-detection and diagnosis.
