Abstract
This paper presents propose of vibration isolating single axle truck for railway vehicle. Single axle truck has several advantages over conventional two axles truck in decreasing weight and curve performance. However, it was said that single axle truck is necessary to improve the isolation performance. Authors proposed new concept single axle truck adding pitching degree of freedom to improve isolation performance in preview study. In this paper, two types of 1/10 scaled model vehicle were designed and made. Test run was done with scale model test plant. From experiments using these test vehicles, it was proved that the proposed vibration isolating single axle truck has high potential for next generation railway vehicle.
