Abstract: The dynamics of railway vehicle on tangent track is dominated by motions in lateral plane commonly refereed as hunting. Hunting is a self-excited oscillation caused by the combined action of conicity of the wheels and creep forces acting in the contact plane between wheel and rail. A railway vehicle becomes unstable beyond a critical speed and therefore, assessment of the critical speed is important for safety and comfort of passenger. In the present work Kalker's linear creep formulation has been used for rail-wheel contact forces. The four geometrical parameters namely gauge, crosslevel, alignment and vertical profile are used to define tangent track irregularity. Track flexibility can be modelled by a one degree of freedom spring mass system. The model is simulated for a given set of nominal parameter values to study the lateral stability behaviour of the wheel set on flexible tangent track. The influence of conicity and wheel radius on stability of railway vehicle is discussed.
