緩和曲線における輪重抜け現象の解明

抄録

A simulation program of vehicle dynamics for analysis of running safety of a railway vehicle was developed. Curving performance simulations were made. Original waveforms obtained from the measured 10m chord's versed sine of the track inspection car were used as the data of track irregularity for our simulation. Simulation results agreed well with measurement results. By using this simulation program, we found that an outer wheel load decreases running on an exit transition curve. The results show that the stiffness of a primary suspension is related to wheel load decrease.
