This paper presents running performance of the vehicles with the single axle truck. Recently, the use of the single axle truck is increasing for the new generation of rail vehicles. In this study theoretical analysis for dynamic stability and curving performance of the single axle truck were made. The asymmetric structure fore-and-aft was proposed to achieve the compatibility between stability and curving performance. Using equivalent stiffness model the condition to satisfy the perfect steering in which the attack angle of the wheelset is zero in curving is obtained. For the high speed stability the proposed asymmetric vehicle with the single axle truck has superior performance. Finally the optimal design for compatibility between stability and curving performance was shown. The numerical simulations and eigenvalue analysis with multibody dynamics software were made and the improved performance of the proposed vehicle with asymmetric structure in the single axle truck was proved.
