PURPOSE: A derailment testing system of a railway vehicle is provided to measure a various and wide change in creep force with respect to derailment under a derailment condition applied to wheels, thereby obtaining data for preventing derailment of a vehicle driving system. CONSTITUTION: A derailment testing system of a railway vehicle comprises a pulley frame(3), a drum(6), a pressing member, and a control member. An axle(2) with a pair of wheels(1) is axially and rotatably connected to the pulley frame. The drum includes a rail ring(4) of a ring shape and rotates by receiving the power of a motor(5). The pressing member forms a derailment condition by applying load to the pulley frame. The control member measures a shape that the wheels are derailed from the rail ring by the load applied by the pressing member, measures a change in creep force, calculates the same, and establish data. |
