摘要本文介绍了如何将用于确定半无限体压力变形的微分变形技术应用于线接触弹流润滑问题的求解方案中。该方法允许使用完全耦合的方法，而无需通常与该技术相关的全矩阵惩罚。这是通过微分挠度法来实现的，该方法以分布式隐式方式而不是特定的显式方式来指定挠度。示出的差分偏转方法，以得到不变的结果，在所需的计算时间从根本上减少。因此，它使弹性和流体动力学方程的充分耦合的固有好处，可用于EHL的解决方案，而没有迄今为止一直与该方法相关的计算罚款。
Abstract This paper describes how a differential deflection technique for determining the deflection due to pressure acting on a semi-infinite body can be incorporated into solution schemes for the elastohydrodynamic lubrication (EHL) line contact problem. The method allows a fully coupled approach to be used without the full matrix penalty usually associated with that technique. This is achieved by the differential deflection method which specifies the deflection in a distributed implicit way rather than a specific explicit way. The differential deflection method is shown to give unchanged results with a radical reduction in the computing time required. It thus makes the inherent benefits of full coupling of the elastic and hydrodynamic equations available to EHL solution schemes without the computational penalty that has hitherto been associated with that approach.
