摘要: 提出了點接觸熱彈流潤滑的簡化數值解。在等溫彈流潤滑完全數值解的計算結果基礎上,通過聯立求解能量方程和熱界面方程等,計算出重載條件下點接觸彈流潤滑狀況下的三維溫度分布。研究了熱彈流問題的溫升規律,并提出了油膜和接觸體表面的最大溫升公式。該公式得到了彈流測溫實驗的初步驗證。Abstract: A simplified solution to the point contact elastohydrody-namiclubrication is presented in this paper. By simultaneously solving the energy equation and the surface temperature equation temperature distributions of three dimensions in contacts are obtained based on pressure and film thickness determined in calculations of isothermal EHL. A group of formulas of the maximum rise in temperature of film and contact surfaces is proposed, which has been verified by experimantal results.
