ABSTRACT:
Viscous damping such as provided by hydraulic dampers is employed to load frictional energy dissipating elements, such as friction wedges used to damp relative movements between the bolster and the side frames in a conventional railway car truck, such that the magnitude of frictional damping provided is dependent upon the velocity of relative movement between the truck bolster and side frames.
