【摘要】 当存在极限剪切应力时,在线接触弹性流体动力润滑中可能出现3种滑移情况,即在两固体表面上均不产生滑移,只在一个表面上产生滑移和在两个表面上同时产生滑移。推导了线接触下允许滑移出现的理想粘塑性润滑剂的润滑方程,并给出了不同情况下的滑移速度的计算方法。更多还原

【Abstract】 The lubrication equation allowing interfadal slippage incorporated into elastohydrodynamic lubrication is derived by making use of the ideal viscoplastic model in line contact. Taking into account of limiting shear stress, three branches may be classified: no interfacial slippage, only slippage at one interface, and simultaneous slippage at two interfaces. The relevant computational methods are given under different circumstances.更多还原
