摘要本文给出了滚动和滑动联合运动下椭圆点接触连接的数值解。这种情况在许多实际应用中很普遍，例如滚动轴承和保形齿轮。在局部点分布和全局线分布的低松弛迭代中，采用了有效的影响牛顿-拉夫逊方法。这种方法可以确定在许多实际应用中遇到的高负载下的压力分布和薄膜形状。一些数值预测已经与实验结果进行了验证。
Abstract The paper presents a numerical solution for elliptical point contact conjunctions under combined rolling and sliding motion. This condition is prevalent in many practical applications, such as rolling element bearings and conformal gears. An effective influence Newton-Raphson method is employed in local point distributed or global line distributed low-relaxation iterations. This method enables determination of the pressure distribution and film shape at high loads such as are encountered in many practical applications. Some of the numerical predictions have been validated against experimental results.
