The effect of yaw damping nonlinearities on the hunting behavior of rail vehicles is studied, using a model for a two-axle truck (bogie) that includes the dynamics of the wheelsets and the truck frame. This study is intended to complement earlier studies by True et al. where they investigated the effect of nonlinearities stemming from creep-creep force saturation and wheel/rail contact forces. The simulation results show that yaw damping can have a mixed effect on the hunting critical speed. In some ranges, increasing damping can actually lower the critical speed, unlike the results commonly obtained from a linear model.
