This paper presents a bond graph model of a free railway wheelset rolling on flexible curved track. A module-based approach is used here. A model of a wheelset considering six degrees of freedom without linearity approximation is created using subsystem models called capsules. Capsules represent various analytical aspects of wheelset dynamics. Different subsystem models are combined to develop a complete bond graph model of a wheelset for simulation on a rigid railway track. For the rail-wheel contact forces (creep forces), a heuristic non-linear formulation is used, which can also be used with slight modification as a linear model for comparative study. Kinematic analysis of the wheelset is done to find out velocities of the contact points on the wheelset. The bond graph is created on the bond graph software SYMBOLS 2000 and simulated for a set of parameter values.
