In the design of railway truck, the axle supporting rigidity is one of the important matters for good running performance. Up to now, the axle supporting rigidity has been selected in the trade-off between running stability and curving performance. This paper deals with a design method for the axle supporting mechnism, which can manage both to secure the running stability and to improve the curving performance. This method utilizes the Bode diagram and makes it possible to evaluate the running performance in the frequency domain. The analytical model of a railway truck is represented as a feedback control system, in which the longitudinal rigidity of the axle supporting mechanism is regarded as the compensator gain. The gain corresponds to the supporting rigidity and it becomes high in the higher frequencies and low in the lower frequencies. An example of the axle supporting mechanism with such frequency characteristics is composed of three elements such as main spring, auxiliary spring and damper. The auxiliary spring and the damper are set in series and placed parallel to the main spring. The effects of the mechanism are shown in the numerical simulation considering track irregularity and the method is confirmed to be available to design the truck with steering ability.
