ON THE SOLUTION OF ELASTOHYDRODYNAMIC SQUEEZE FILMS

A solution scheme for the squeeze-film problem using the Newton-Raphson method with a tangential matrix is presented. The integration of the elasticity equation is done with the aid of isoparametric elements, and the film thickness under a sinusoidal load is obtained. A new squeeze-suction phenomenon which shows the possibility of maintaining the fluid film under cyclic positive load conditions is observed for small load and period and large compliance parameter cases. This could be an interesting result in applications such as viscous hydroplaning.
