Responses of test train running on track irregularities artificially set on SHINKANSEN and results of vehicle dynamics simulation were compared at a speed up to 2l0km/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. Then the state of track irregularity artificially set was precisely investigated and an enlargement of gauge in the section of 20m wave length was found. And simulation of the response assuming the gauge enlargement was nearly identical with that of measurements. In this report, the influence of wave length and gauge variation on the response to track irregularity mentioned above is analyzed by comparing between measurements and simulation. Besides, using the same simulation program, the influence of gauge variation on carbody hunting motion of a new high speed SHINKANSEN train which has soft suspension between carbody and bogie due to bolsterless bogie is studied.
