Abstract: A design methodology is developed for passenger vehicle rail trucks in which primary and secondary suspension parameters and wheel/rail parameters are determined to meet a set of dynamic performance indices. The methodology partitions the design task into two basic tradeoff studies: (1) a stability-curving tradeoff and (2) a lateral ride quality-secondary stroke tradeoff. The design methodology is illustrated with both high-speed intercity and lower-speed urban rail truck designs.

Keywords: rail vehicle dynamics; rail vehicle design; rail truck design; bogie design; hunting; curving; ride quality; computational performance modelling; design methodology.
