The Alsthom truck for Co-Co electric locomotives, the S.I.G. truck for electric railcars, the Werkspoor truck for electric railcars, and Allan truck for diesel-electric railcars are photographed showing the spring systems. The action of friction (Coulomb) and hydraulic (viscous) damping is illustrated with the aid of force-displacement diagrams. The effect of friction and hydraulic damping on force transmission and oscillation amplitude ratio as a function of frequency ratio and the effect of oscillation amplitude on dynamic stiffness of leaf springs as affected by friction are also illustrated. The advantages of friction damping are mentioned.
