The invention discloses an instrumented wheelset calibration test bed. The instrumented wheelset calibration test bed comprises a gantry framework, a vertical load testing unit, a longitudinal load testing unit, a transverse load testing unit and steel rails; the vertical load testing unit comprises a vertical actuator for applying a vertical load and a vertical force testing unit which is arranged under the installation position of an instrumented wheelset and used for testing the vertical load of the instrumented wheelset, the vertical actuator is hung on a cross beam of the gantry framework, and the lower portion of the vertical actuator is used for being hinged with the instrumented wheelset; the longitudinal load testing unit comprises a longitudinal actuator for applying a longitudinal load, and the front end of the longitudinal actuator is hinged with the vertical force testing unit; and the transverse load testing unit comprises a transverse actuator for applying a transverse load, and the two ends of the transverse actuator are used for abutting against a set of wheels of the instrumented wheelset respectively. According to the instrumented wheelset calibration test bed, the various directions can achieve loading independently or in a combined mode, and by means of three-direction comprehensive calibration, calibration on instrumented wheelsets of different truck models can be met.
Description
technical field [0001] The invention relates to the technical field of rail vehicles, and more specifically relates to a calibration test bench for a force-measuring wheel set. Background technique [0002] The dynamic performance test of rail traffic involves vehicle safety, including stability index (derailment coefficient, wheel weight unloading ratio, axle lateral force, overturning coefficient) test and stability index test. The completion of this test is a prerequisite for the normal on-line operation of the vehicle, so it has received widespread attention from all parties. At present, all dynamic performance tests need to use force-measuring wheelsets. The production and use of force-measuring wheelsets is a symbol of technical strength in the field of rail transit testing. The production level and calibration accuracy of the force measuring wheel set directly affect the effect of the online test of the dynamic test, and have a direct relationship with the reliabilit...
