Originální abstrakt
In this work, the thermal elastohydrodynamic lubrication in elliptical contact under impact motion is investigated numerically by altering oil viscosity and elliptical ratio. The impact-rebound time is shortened with the increase of the elliptical ratio, while a smaller ambient oil viscosity extends the impact-rebound time. Generally speaking, a larger elliptical ratio reduces the maximum load-carrying capacity, increases the value of the minimum film thickness, and lowers the temperature rise. A smaller oil viscosity lowers the pressure and temperature rises and reduces the film thickness.
