IMPROVED SUSPENSION FOR 100-TON CARS ON ROUGH TRACK
American Steel Foundries set out to develop a freight car suspension defined as a highly refined, state-of-the-art, three-piece truck designed as a system rather than a collection of components. This article discusses suspension reserve work capacity, optimum damping, design process, ride quality findings in the vertical, lateral and rocking modes, and the determination of the wheel-rail forces as evidenced by factors such as flange wear and truck component wear.
