用非牛顿流体热弹流润滑方程对磨合过程进行了解算.解算中考虑了光滑表面的轮廓磨损与不同高度和斜度的微突体磨损对润滑特性的影响.分析结果表明:在重载条件下表面轮廓磨损不利于润滑,而表面微突体的磨损则有利于润滑;当同时考虑表面轮廓和粗糙度时,在一定磨损高度内,磨损显著增加润滑膜的最小膜厚,从而有利于润滑
The non-Newtonian fluid hyperelastic lubrication equation is used to solve the running-in process, and the influence of the profile wear on the smooth surface and the microprotrusions with different heights and slopes on the lubrication characteristics is considered in the solution. The analysis results show that: Under the conditions of surface profile wear is not conducive to lubrication, and surface micro-convex body wear is conducive to lubrication; while taking into account the surface profile and roughness, within a certain wear height, the wear significantly increases the minimum thickness of the lubricating film, which is conducive to lubricating
