ABSTRACT: A procedure for the selection of rail passenger truck design parameters to meet dynamic performance indices has been developed. The procedure is based upon partitioning the design task into three trade-off studies: (1) a vertical ride quality-secondary stroke trade-off, (2) a lateral ride quality-second stroke trade-off, and (3) a stability curving trade-off. The procedure is illustrated with the selection of design parameters for an intercity 130-mph vehicle and an urban 80-mph vehicle.
