Study on Dynamic Parameters in Finite Line Contact
A transient elastohydrodynamic lubrication (TEHL) model was developed for finite line contact with considering the dynamic behavior,and the numerical solution for lubrication was obtained.The free vibration model of single degree with damping was combined and the relative displacement was selected as the free vibration standard.The numerical results demonstrate that film thickness fluctuation and local pressure peak are established in the inlet region and spread to the outlet region.As the vibration time increases,the result eventually reaches a steady state solution.The stiffness is increased with the increasing of load.The changes of damping are different in various working conditions.
