VEHICLE TRAVELLING SWING/NOISE ANALYZING SYSTEM, VEHICLE TRAVELLING SWING/NOISE ANALYZING METHOD, VEHICLE TRAVELLING NOISE ANALYZING SYSTEM, AND VEHICLE TRAVELLING NOISE ANALYZING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a vehicle traveling swing/noise analyzing system, which accurately provides swing measurement values and/or cabin noise measurement values with high position accuracy and high distance accuracy in the traveling test of a rolling stock, and performs tests at low cost without applying a load on a measurer. SOLUTION: In this system, a three-axis acceleration sensor 11 detecting the vibrating acceleration of a vehicle traveling on tracks in the longitudinal, lateral, and vertical directions, a noise meter 12, a GPS antenna 13, and a GPS receiver 14 are installed on the vehicle. The position information of the vehicle is corrected by the position information acquired by a signal received by the GPS receiver 14 through the GPS antenna 13 and the longitudinal acceleration of the vehicle detected by the three-axis accelerator sensor 11. The position information of the vehicle is corrected by a station stop signal inputted by the measurer when the vehicle stops at a station and/or a structure signal inputted by the measurer when the vehicle passes through a structure.
