Abstract

In this paper two novel evaluations of the Tevaarwerk-Johnson model are made. In the first evaluation, the model predictions are compared, to traction data measured between a ball and a flat disk in an “optical EHL” style rig under conditions of constant spin velocity and various amounts of lateral sliding. In the second evaluation, six sets of data taken from the literature were used, wherein each set comprised a traction curve taken at fixed rolling speed, load, and temperature, and, for those same conditions, a plot, of measured spin torque against imposed spinning velocity. This investigation generally confirms the usefulness of the Tevaanuerk-Johnson model for predicting, when the Deborah number is sufficiently large, the joint effect of lateral sliding and spin on longitudinal traction force and for predicting the torque due to spin.
