摘要
对旋转机械中常见的转子偏心、松动、裂纹、碰摩四种故障诊断的非线性分析方法进行了综述,探讨了这些机械系统中可能出现的复杂运动,比较了各种方法的优缺点并对其发展方向做了展望。
The present development of nonlinear dynamic analysis method to detect the four kinds of machine faults, such as rotor eccentricity, loosen, crack and rubbing are reviewed. The possibly complex movement occurred in these mechanical systems are discussed in details. The advantages and disadvantages of different methods are compared to give the future research direction.
