摘要
基于Ostwald模型建立的脂润滑控制方程与能量方程联合求解,通过压力-温度的循环来计算线接触脂润滑热弹性流体动力润滑数值解。分析了一般工况参数对润滑膜压力分布和润滑膜形状的影响,探讨了不同工况下热效应对脂润滑弹流数值解的影响。
The numerical solution of thermal elastohydrodynamics of grease lubrication in line contact is calculated based on combined solution of grease lubrication control equations from Ostwald＇s model and energy equations by pressure - temperature calculation cycle. The effect of normal running parameters on pressure distribution and shape of oil film is analyzed, and the effect of thermal effect on the solutions is discussed under different running conditions.
