Abstract

The authors are to be congratulated for presenting this study of the effect of nonlinear wheel/ rail contact geometry on stability of rail vehicles. Although, nonlinear characteristics of wheel/rail interaction are presently being studied by various investigators, in writers' opinion this paper is a significant published work in this area.The model presented in the paper has the motion of a wheel-set described by two parameters-lateral displacement and yaw rotation. 1
