Abstract A railway vehicle becomes unstable beyond a critical speed. Assessment of the critical speed is important for safety and passenger comfort. Bond graph model of a wheelset system on flexible tangent track has been created with six degrees of freedom. Kalker’s linear creep formulation has been used for rail-wheel contact forces. A bump type of irregularity has been considered on the track. The model is simulated for a given set of nominal parameters value to study the lateral stability behavior of the wheel set on flexible tangent track.
