The axle supporting system which satisfy both steering and stability has been proposed previously. To fully utilize the effect of this system, it is important to decide the parameter under theoretical ground. In this study, parameter design method of this system is shown step by step, considering operation speed, curve negotiation speed, and so on. Here, the value of the parameter is also considered to be within physically possible range for railway vehicle. To show the effect of the parametrized axle supporting system, numerical simulation is performed for two different pairs of parameter, assuming high-speed inter-city train and low-speed mass transit one. Calculation results about attack angle, lateral force, and wear index show that they are all improved after system introduced.
