Effect of Track Measuring Beam on the Dynamic Properties of Rail Inspection Car

Abstract:

The track measuring beam is installed in the bogie frame to measure the geometry parameters of the rail. In this paper, the dynamic model of the inspection car was established in order to compare the dynamic properties of the vehicle with and without track measuring beam installation. The motion stability, ride quality, vibration acceleration and curve negotiation performance of the vehicle after the track measuring beam installed were investigated. The results show that after the track measuring beam installation the critical velocity of the inspection car decreases, but the running at speed of 120km/h can be guaranteed. The track measuring beam has no influence on the ride quality and curve negotiation performance and the effect of it on vibration mode is little.
