摘要
以简化推力轴承为对象 ,理论上证明了推力轴承运行时存在热不稳定性 ,采用小扰动分析法得到了油膜温度的扰动方程 ,应用简正模态分析法推导了无量纲热不稳定性准则数以及推力轴承运行的热不稳定性准则 .
It was theoretically proven that thermal instability exists during operations for thrust bearings based on an infinitely wide thrust bearing. The equation of oil film temperature disturbance is derived with the small perturbation method, and the non-dimensional thermal instability number and the thermal instability guidelines of operation for thrust bearings are obtained applying the standard normal mode analysis.
