摘　　要：通过SPH方法的基本理论并结合Navier-Stokes方程,利用C语言研发了考虑油膜非线性流动性行为的软件系统,对滚动轴承微接触区域油膜进行了假设并建立了SPH数值计算模型,用不同的油膜粘度系数对滚动轴承微接触区域在富油条件下的油膜流动行为进行了探讨。根据极速启动的实际工况,模拟富油静压状态下在一定的粘度值不同时刻油膜粒子的压强变化,结果表明油膜压强在不同时刻呈现非线性变化的规律。并通过对粘度值的改变,探讨其对油膜粒子压强的影响,以揭示滚动轴承在复杂接触区域中油膜粒子的运动特性。Combined the basic theory of SPH method with the Navier - Stokes equations, using C language to write a software system considering the nonlinear liquidity behavior of the oil film, by means of hypothesis for the geometric model of the rolling bearing, obtaining the model of rolling bearing for SPH method. And then discussed the flowing behavior of oil particles in the micro contact area of rolling ty. According to the actual working condition of rapid boot, simulating the pressure viscosity, and the research shows the pressure of oil film is different in different time. bearing in different viscosichange of oil film in certain And discussed its influence on the pressure of the oil film particles by the change of dynamic viscosity, and then reveal the movement characteristics of roiling bearing in complex contact area.
