以往的点接触弹流润滑研究往往局限于分析卷吸速度方向与接触椭圆短轴相重合的工况.但在实际工程问题中,有时卷吸速度方向与接触椭圆长轴相重合,有时卷吸速度方向与接触椭圆的对称轴成一夹角.针对这一问题,该文提出了一种独特的解决方法.压力和膜厚分析分别采用多重网格和多重网格积分法.无论卷吸速度的方向如何,总让X轴与速度方向一致,而Y方向速度永远等于0.这样任意卷吸速度方向的工况和卷吸速度与接触椭圆短轴相重合的工况相比只需改变膜厚方向即可.“,”Elastohydrodynamic studies have almost entirely been restricted to the case where lubricant entrainment coincided with the minor axis of the Hertzian contact ellipse.But in the practical engineering problems, the lubricant entrainment sometimes corresponds with the major axis of the ellipse, and is sometimes at an angle to the minor axis.Aimed at such problems, this paper presents a particular solution.Multingrid and multilevel integration techniques are adopted to calculate the pressure and film thickness respectively. During the calculation, the direction of X - axis is always set to coincide with the lubricant entrainment, that is, the velccity of Y - direction is equal to zero, no matter how is the direction of entrain-ment.Then the film thickness's equation should be varied to the corresponding form, and all the other equations are unchanged, for the purpose of the problem of an arbitrary entrainment, as compared with the case where lubricant entrainment corresponds to the minor axis of Hertzian contact ellipse.
