dc.description.abstract | This paper describes the kinematics used for the calculation of track geometric irregularities
of a new Track Geometry Measuring System (TGMS) to be installed in railway vehicles. The TGMS
includes a computer for data acquisition and process, a set of sensors including an inertial measuring
unit (IMU, 3D gyroscope and 3D accelerometer), two video cameras and an encoder. The kinematic
description, that is borrowed from the multibody dynamics analysis of railway vehicles used in
computer simulation codes, is used to calculate the relative motion between the vehicle and the track,
and also for the computer vision system and its calibration. The multibody framework is thus used
to find the formulas that are needed to calculate the track irregularities (gauge, cross-level, alignment
and vertical profile) as a function of sensor data. The TGMS has been experimentally tested in a 1:10
scaled vehicle and track specifically designed for this investigation. The geometric irregularities of a
90 m-scale track have been measured with an alternative and accurate method and the results are
compared with the results of the TGMS. Results show a good agreement between both methods of
calculation of the geometric irregularities. | es |
