Shear pads are devices used to improve vehicle dynamics performance on heavy haul railways wagons. In this work, we present a method to determine the elastic properties of such components using experimental/numerical approach. The final goal is to provide adequate input to multi-body analysis software commonly applied to study and design railroad vehicles. We also considered the effect of side frame compliance to primary suspension performance, a influence that is often neglected on this type of study. Our results show that the application of shear pads can indeed promote a significant reduction of wheel and rail wear by decreasing the total frictional energy . We also show that, under the simulated conditions, the most important stiffness coefficient to wear is the longitudinal one.
