The Pressure and Film Thickness Distributions in Point Elastohydrodynamic Contact Under Dynamic Load

Isothermal elastohydrodynamic (EHD) problem for dynamically loaded lubricated point contact is formulated and studied numerically. Mathematical formulation is based on the time depending nonlinear system of integrodifferential equations. In order to determine the location of the exit (free) boundary the problem is formulated as a problem of complementarity. The dimensionless system of equations and inequalities is solved using Newton method. Peculiarities of the influence of non-steady state (sinusoidal) loading on pressure and film thickness in the point EHD contact are shown.
