In this paper, the authors theoretically analyze the forced hunting of a high-speed vehicle, which runs on a rail with sinusoidal irregularity, in reference to lateral direction of the rail. The authors used the half-body vehicle model having a small clearance in the connection position between the truck frame and the bolster anchor, where the spring and friction are connected in series against truck turning. Consequently, the authors clearly showed that there appeared some very complicated nonlinear phenomena in comparison with the resonance curves of no body. Then, the authors showed the influence of various values on the vehicle vibration, for example, the frictional force of the side bearer, the wheel tread conicity, the yawing damper, and the turning stiffness of the truck. Further-more, the authors proposed target values for the designing of vehicles.
