Track Irregularity PSD
The numerical simulation is a suitable method to get the practical riding comfort of railway vehicles by calculation. Since the running simulation of the vehicle needs realistic track irregularity shapes, artificial generation of them makes the simulation method more efficient tool for improvement of suspension and running gear systems. This paper sums up the artificial generation from track irregularity PSD by the inverse Fourier transform and describes the process for prediction of the riding comfort taking an example of the lateral vibration of a Shinkansen electric car caused by alignment irregularities. In this process, the simulation is executed by the Runge-Kutta-Gill method, the acceleration PSDs of the car body are analyzed from simulation results by the Fourier transform and the Riding Quality Level L_T is, calculated as the index for quantitative estimation of the riding comfort.
