An FEM model of rotor-bearing system was set up for a single-span-two-disc test rig to obtain such model parameters as the first and second order natural frequency and vibration mode vectors.
以某单跨双盘模型转子实验台为例,建立了该转子-轴承系统有限元模型,得到转子系统前两阶固有频率和振型向量等模态参数·基于转子系统碰摩力的周期性假设,利用模态扩展方法,对故障和健康转子系统振动信号的残差矩阵进行傅立叶级数的分频谐波近似,估算得到转子-轴承各节点的碰摩力·根据转子各结点估算碰摩力的频谱、时序以及等效碰摩力幅确定碰摩发生位置,进而对碰摩故障的程度进行定性评估·试验表明,这种方法可以对转子周期性碰摩进行较精确的诊断,并为其他转子-轴承系统故障诊断提供参考
