Assessment of a Simplified Wheel/Rail Contact Model and Kalker’s Linear Theory from the Perspective of Hunting Instability

Öz

This paper investigates the performance of a simplified wheel/rail contact modeling approach that can be implemented to dynamics analysis of railway vehicles. The scope is limited to a two-axle bogie system and the problem is investigated from the hunting instability perspective. Accordingly, a mathematical model of a two-axle bogie with elastically connected wheelsets is developed. The governing equations of the proposed four degree of freedom mathematical model are obtained. These equations are then first solved analytically by considering a simplified approach for the interfacial forces at the wheel/rail contact interface. Second, the contact forces are calculated by using Kalker’s linear theory, and the corresponding nonlinear governing equations are solved numerically. Based on the results, it is observed that the analytical and numerical solutions show a good match. Hence, it is concluded that the simplified wheel/rail contact modeling approach can represent the dynamics of the system successfully, especially when the system is in a stable state for hunting behavior. Third, the corresponding eigenvalue problem is formulated from the linear equations, and complex eigenvalues are calculated over the operational speed range of the bogie. It is observed that the natural frequencies of the system are speed-dependent, and either one or both of the wheelsets may become unstable at certain parameter sets. Finally, stability maps are generated for several parameters, and a better understanding of the effects of system parameters on the stability of two-axle bogie is obtained.
