It is a full-scale testing platform built for the investigation of derailment mechanisms. The length of the track is 120 m long and is employed to research derailment mechanisms of bogies running on track. The rig is composed of a track system, guide rail, traction system, trailer wagon, bogie, load application device, electric cylinder servo loading device, safety rope regulation device, angle of attack regulation device, and so on.

Functions:

●  Simulate the process of wheel climbing at low speeds

●  Study derailment mechanisms

●  Study and further understand wheel/rail matching relationships

●  Obtain a better understanding of the mechanisms underlying the dynamic interaction between wheels and rails

●  Study the critical angles of derailment under different conditions

●  Experiment and study the geometric contact relationship of different types of wheel profiles

●  Study wheel/rail interaction effects with respect to track geometry such as different rail distance, horizontal and sloped tracks, etc.

Main technical parameters:

●  Maximum vertical load: 160 kN.

●  Maximum horizontal load: 100 kN.

●  Maximum running speed: 30 km/h.

●  Maximum angle of attack: 5 degrees.
