摘要：

The running-in characteristics of an EHL line contact is investigated in an effort to optimize its steady-state performance. During the running-in process, asperities experience both elastic and plastic contact and as a result of the plastic deformation, the asperity heights change. Extensive simulations are performed to quantify the change in the arithmetic average of asperity heights as a function of operating conditions, and appropriate relationships are developed for design applications. It is also shown that corresponding to a specified load, there exist a value of speed which results in the lowest steady-state friction. The significance of this finding is that if during the running-in period the speed is maintained at this optimum value, the steady-state power loss and wear will be minimum. (C) 2013 Elsevier B.V.
