渐开线直齿圆柱齿轮的稳态和瞬态弹流的数值计算与分析

N UMERICAL EVALUATION INVESTIGATION OF THE STEADY AND TRANSIENT ELASTOHYDRODYNAMIC LUBRICATION(EHL) OF INVOLUTE SPUR GEAR

应用Ｎｅｗｔｏｎ－Ｒａｐｈｓｏｎ法和低松弛法，在计入挤压效应的情况下，对渐开线直齿圆柱齿轮的弹流润滑（ＥＨＬ）进行了瞬态的数值计算与分析，得到了高精度的收敛解。并与稳态计算进行了对比，发现了瞬态弹流润滑的一些特征。

Considering squeezing effect and comparing to the results of steady elastohydrodynamic lubrication(EHL),the numeirical analysis and evaluation of the transient EHL of involute spur gear have been Performed using Newton-Raphson and underrelaxation method and a convergence solution of high Precision is afforded.The Paper attain some fundamental characteristics of transient EHL.
