摘　　要：分析了转子系統碰摩故障特征,提出了转子系统碰摩的多尺度非线性信号分析方法.碰摩故障诊断实例表明,与经典线性信号的时域和频域分析相比,多尺度非线性信号分析方法具有明显的局部特征优势.The faulty characteristics of rotor system rubbing-impact are analyzed in the paper. The paper presents the multi-dimensioned nonlinear signal analysis method of rotary rubbing-impact. The example of engineering practice shows the multi-dimensioned nonlinear method has more advantage of the local characters than traditional linear one in time field and frequency.
