摘要
考虑椭圆抛物面织构,研究其对滑动轴承性能的影响。以径向滑动轴承为研究对象,建立具有椭圆抛物面织构的滑动轴承雷诺方程。采用有限差分对方程进行离散,结合超松弛迭代法进行求解,得到滑动轴承的性能参数值,并与光滑滑动轴承进行对比。结果表明:单一凹/凸表面织构下,随着织构几何参数的变化,承载力和摩擦因数存在相同的变化趋势,与光滑滑动轴承相比,轴承的性能没有得到有效的提升。考虑凹凸复合表面织构,研究其对滑动轴承性能的影响。结果表明,存在最优织构几何参数使得滑动轴承承载力增大,摩擦因数降低,滑动轴承的性能得到有效的提升。
The effects of elliptical paraboloid texture on sliding bearing performance were studied. Taking radial sliding bearing as the research object,Reynolds equation of a sliding bearing with elliptical paraboloid texture was established.Using the finite difference method to discretize the equation and solving it with thesymmetric successive overrelaxation method,the performance parameter values of the sliding bearing were obtained and compared with smooth sliding bearing.The result shows that,for the single concave or convex surface texture,there is the same trend of bearing capacity and friction coefficient for the sliding bearing with the change of texture geometric parameters,and compared with smooth sliding bearing,the performance of the bearing has not been effectively improved. Considering the concave convex compound surface texture,the effects of it on sliding bearing performance were studied. It is found that there exists optimum texture geometric parameters which can increase the bearing capacity and reduce the friction coefficient of the sliding bearing,and the performance of the sliding bearing can be improved effectively.
