摘　　要：从推力盘的实际工作情况出发，用数值计算联立求解雷诺方程、弹性位移方程、油膜厚度方程、润滑油粘度和密度方程、速度方程、能量方程以及界面温度方程，得出了高速工况下推力盘热弹流润滑接触问题的完全数值解，计算出平均速度、载荷、锥角、润滑油粘度与推力盘最小油膜厚度的关系。Based on the real working condition, this paper presented a full numerical solution to the problem of thermal elasto hydrodynamic lubrication for the conic thrust disks under high speed condition. The relations of the minimum film thickness with the mean velocity, load, conic angle and the viscosity of oil have been computed. The theoretical calculation was verified by Sapekov′s experimental results.
