标高对转子-滑动轴承系统动力学特性影响研究

摘要

通过理论和实验研究了多跨转子-轴承系统标高对其轴承载荷分配、临界转速及稳定性的影响规律.结果显示,轴承标高变化对柔性转子临界转速影响较小,但对轴系稳定性有较大影响.研究结论为多跨轴系标高设计及现场调试提供依据.%In this paper, the bearing load distribution, the critical speed and the stability of multi-span rotor-bearing system was investegated. The results indicated that bearing elevation had little influence on the critical speed of flexible rotor-bearing system, but had much influence on the stability. The conclusion can be used in the design of multi-span rotor-bearing system and the pratieal engineer.
