紊流滑动轴承-转子系统的稳定性
Stability of rotor system supported by sliding bearing with turbulent effect
摘要
Abstract
The much more sliding bearings operate under the turbulent condition owing to an increase in the size and the linear velocity of the rotor in the bearing‐rotor system .The analytical expression of non‐linear oil film forces of the turbulent sliding bearings is obtained by the Sommerfeld transformation under the infinitely long bearing assumption ,and then a rotor system with the sliding bearings support is mod‐eled .The stability of the bearing‐rotor system is determined by Routh‐Hurwitz criteria .The effect of turbulence on the stiffness coefficient ,damping coefficient ,the critical speed of the rotor and the whirl frequency ratio at the critical speed are investigated .关键词
