Comparison between Data from Test Train Running on Track Irregularities Artificially Set and Result of Vehicle Dynamics Simulation (Influence of Track Gauge Variation on Rail Vehicle Dynamics)

摘要

Resposes of test train running on track irregularities artificially set on SHINKANSEN and results of vehicle dynamics simulation were compared at a speed up to 210km/h. In comparison between the measurements and simulation using basic parameters, the response to alignment irregularity of the measurements and simulation for the wave length longer than 40m is nearly identical, although that of simulation becomes apparently larger than that of measurements for wave length of 20m.
