Structural and Dynamical Analyses of New Gauge-Changeable Bogies of Railway Passenger Car

Application and development of gauge-changeable bogies abroad are briefly introduced. According to the situation in China, a new scheme for gauge-changeable bogies was proposed, its structure was presented, and its dynamic performances were analyzed with numerical simulation. The results show that the proposed scheme is basically feasible, with good hunting stability and riding quality, except that the curving performance needs to be improved.
