APPARATUS FOR TESTING WHEEL OF RAILWAY VEHICLE AND RAIL WITH ELASTIC MEMBER FOR REMOVING NOISE OF THRUST LOAD OR RADIAL LOAD

摘要

PURPOSE: A device for testing wheel of railway vehicle and a rail with elastic member for removing noise of thrust load or radial load is provided to improve high frequency component of load applied to a wheel specimen. CONSTITUTION: A device for testing wheel of railway vehicle comprises a wheel specimen driving part(100), a rail specimen driving part(300) and an elastic member. The wheel specimen driving part comprises a load loader(110), a side loader(140) and a wheel operation part(170) The load loader applies load to a wheel specimen at a radial direction of a wheel specimen(10). The side loader is arranged in one side of the wheel axle and applies side load to the wheel specimen. The wheel specimen and wheel axle are installed on the wheel operation part to rotate the wheel axle and wheel specimen. The rail specimen driving part is separately arranged in the wheel axle and the wheel specimen driving part. The elastic member eliminates the high frequency component of the applied load.
