摘要
针对实际中存在转、静件不均匀膨胀导致碰摩的情况,把静子局部膨胀当作静子局部存在的凸起缺陷考虑,以此建立了碰摩力模型,研究了其振动特性的变化情况,为实际碰摩故障诊断提供了理论依据。
As there may be asymmetry expand on rotor or stator part of rotor system which would bring us mbimpact. In this paper, we consider the asymmetry expand as part - defect - tuber, and set up the model,then the vibration characteristic was studied. As a result, this study provides thetheoretical foundation for the fault diagnosis of the rotor system.
