| 摘 要： | 采用传递矩阵法计算了轴承标高变化对多跨轴系各轴承负荷分析，动特性系数、临界转速、不平衡响应及稳定性的影响，计算结果表明轴表标高对轴系振动及稳定性均有一定影响，对于稳定性不足的轴承需监测其标高变化。

| Abstract: | A transfer matrix method is introduced to calculate the bearing loads, drnamic coefficients of the oil film bearings, the critical speeds, unbalance responses and instable speeds of the multi-span shafts on various height mark of bearings. Calculating results show that height mark has great effects on the vibration and stability of the shafts. It is necessary to monitor the height mark variation of unstable bearings. |
