摘要
根据旋转机械动态特性的特点,研究了转子不对中和油膜失稳的故障问题,并分别建立数学模型,讨论其产生机理,研究二者的耦合作用,改变了以往将二者单独进行研究的作法。为旋转机械的故障诊断机理分析提供了有实用价值的方法,具有一定的工程应用意义。
According to the features of turnning machine, the failure of oil film instability and shaft system misalignment was analyzed, The dynamic model was established and the mechanism was discussed. The coupling effect of oil film instability and shaft system misalignment was studied, which provides a practical way for the fault diagnosis of turnning machine.
