• We analysed theoretically the lateral forced vibrations observed in a high speed truck when it runs on a rail with sinusoidal irregularity, assuming that the truck has spring and friction in series against truck turning. The analysis revealed that the running stability of truck is affected by various factors: the wheel tread conicity, the rotational stiffness of truck, the friction of side bearers, the creep coefficient, the viscous damping against truck turning, the flange clearance between the wheel and the rail and the lateral stiffness of rail and so on. Then, we made clear that the wheel tread conicity is one of the most important factors to prevent the lateral forced vibrations caused by rail irregularity, though for its prevention from practical point of view, it will be desirable to obtain an adequate restoring force against truck turning. The calculated results will be helpful for designing of the high speed trucks.
