A symmetric wheelset with an elasto-damper coupling between the wheels is used to investigate the effect of coupling and primary stiffness and damping on the vehicle critical speed. Different suspension parameters are considered. Stability boundaries for various conditions are presented. The dynamic model of the elasto-damper–coupled wheelset is validated using published results. Both coupler and primary suspensions can dramatically affect the vehicle stability, and optimal parameters can be used to improve the vehicle performance over that of the conventional system.
