滑动轴承润滑机理及速度系数分析

摘要

Based on five-point difference scheme of finite difference method and using over-relaxation iteration method to solve two-dimensional Reynolds equation, the oil film pressure distribution of a sliding bearing was simulated with MATLAB programming; and the impacts of bearing dimensionless velocity coefficient on dimensionless carrying capacity and dynamic characteristics was further studied.%基于有限差分法中的五点差分格式,采用超松弛迭代法对二堆ReynoIds方程进行求解.然后通过MATLAB编程,仿真出滑动轴承油膜压力分布,并进一步研究了轴承无量纲速度系数对轴承无量纲承载力以及动力特性的影响.
