n a railway vehicle, the wheel tread profile is one of the most important factors which have influenced running stability and safety. In current high speed railway vehicles, the wheel tread profile is compared to worn profiles, and is used for the improvement of running characteristics and to simplify maintenance and the control. The authors have theoretically analysed in detail the geometrical contact between the wheel tread profile consisting of compound circular arc-forms and the rail. Then, a describing function method is applied to the theoretical calculation for the SHINKANSEN truck hunting having six-degrees of freedom. Consequently, it is made clear that the truck hunting is influenced by many factors, such as non-linearity wheel tread conicity, clearance between the truck frame and the bolster anchor, non-linear characteristics of the turning moment of truck and the supporting stiffness of the axle and so on. Furthermore, the guiding principle for the improvement of the running capacity and the target values of the design for high speed trucks are presented.
