前已指出,在最简单的弹性流体动力学问题中,便需要联解计入润滑油压粘关系的流体动力方程和弹性力学方程.在分析中常作如下简化:(1)位移是按处于平面应变状态的半无限固体来计算.(2)侧泄和边缘效应影响略去不计.由于接触区宽度(2b)远小于圆柱的长度L,因而不计端泄影响是合理的.另
It has been previously pointed out that in the simplest problems of elastohydrodynamics, the hydrodynamic equations and elastic mechanics equations that take into account the pressure-viscosity relationship of the lubricating oil need to be solved. The analysis is often simplified as follows: (1) (2) The effects of side leakage and edge effect are negligible.It is reasonable not to consider the effect of end discharge because the width (2b) of the contact zone is far less than the length L of the cylinder.
