PERFORMANCE CHARACTERISTICS OF FREIGHT-CAR TRUCKS DETERMINED THROUGH ROAD TESTING

The behavior of railroad freight-car trucks is described in relation to response modes developed within the truck structure and the freight car. A 70-ton-capacity mechanical refrigerator car equipped with conventional- style, friction-snubbed three-piece trucks was tested under a variety of conditions to develop performance behavior over the speed range of 10-79 mph. Testing was conducted on tangent track and curved track. Response behavior is described in graphs showing frequencies and amplitudes of significant descriptors.
