RAIL CAR TEST STAND

FIELD: railway transport; testing facilities. ^ SUBSTANCE: invention is designed for use in laboratories for revealing vibrations of cars similar to vibrations of cars in motion. Proposed stand is secured on concrete-lined trench equipped at top with coupling device for fastening car with built-in dynamometer for measuring horizontal forces in its frame. Stand is furnished also with rotary complex arranged on support in trench bottom. Rotary complex is made in form of crawler propulsion unit with engine and transmission, on each track of which sections of rail track with preset gauge for rail car tested in the open are installed. Bogies of car rest on rail track. Height of support for mounting rotary complex provides free sagging of crawler propulsion unit. Stand is furnished with vibrator suspended from car bottom through distributing beam. Points of application of load of said beam are near car body pivot bearings. ^ EFFECT: dispensing with additional load-lifting devices simulating forces acting on car under various on car under various operating conditions. ^ 3 cl, 4 dwg
