| description | PROBLEM TO BE SOLVED: To provide a rail car rocking measuring instrument capable of performing unmanned measurement of rail car rocking in a running test of a rail car and of achieving labor-saving in measuring the car rocking and consequently cost reduction, and to provide a method of measuring the car rocking.SOLUTION: The rail car rocking measuring instrument measures the car rocking by detecting acceleration in the longitudinal direction, transverse direction and vertical direction of the car by a 3-axis acceleration sensor 12 installed on the car running on a track. The instrument is structured so as to determine that the car is stopped at a station when fluctuation of acceleration in the longitudinal direction, transverse direction and vertical direction of the car detected by the 3-axis acceleration sensor 12 is 0.2 m/sover the period of at least 15 seconds. In addition, the instrument identifies a station where the car is stopped by measuring car inclination from values of acceleration in the longitudinal direction, transverse direction and vertical direction of the car while the car is stopped at a station and by comparing with database created beforehand of the car inclination while the car is stopped at each station. |
