Fast evaluation of friction forces in traction-drive contacts including thermal effects

摘要

In automotive traction drives, power is transmitted by friction forces. The friction forces result from the shear stresses developed in lubricated and highly laded contacts be- tween rolling bodies. Due to the kinematics of a traction drive, shear velocities occur in both the rolling direction and perpendicular to it. Due to these shear velocities and by normal pressure, the lubricant is forced to build up shear stresses. The increase of the shear stresses may be modelled by a nonlinear viscous element.
