CORROSION EFFECTS OF RAIL FASTENING DEVICE ELEMENTS ON JOINT INTEGRITY Dragutin Georgijević, Zijah Burzić Military Technical Institute, Belgrade |
Abstract The paper indicates on the corrosion effects of fastening device elements, sleeper screw and spring, on rail fastening force. Laboratory and in-situ testing shows that corrosion increases the friction coefficient, thus requiring a higher torque on sleeper screw to achieve necessary fastening force. Weak joint of rail and sleeper disarrange fastening device integrity and reduce life of its elements. Keywords: testing, railroad rail, corrosion, fastening moment, friction |
