Thermal Elastohydrodynamic Lubrication of Rolling/Sliding Line Contacts
Journal of Tribology, 1992The solution of thermal elastohydrodynamic lubrication of rolling/sliding line contacts has been obtained. The Newton-Raphson technique was used to solve the simultaneous system of Reynolds and elasticity equations. The energy equation with boundary conditions was solved by the finite-difference method.
