PROBLEMS OF INTERACTION OF VEHICLES AND TRACK--WORN PROFILES OF RAIL HEADS AND WHEEL TYRES

As a result of a large number of tests it has been proved that service wear on wheel tires and rail heads leads to definite profiles. These worn profiles are to a large degree independent of the initial profiles of tires and rail heads. In the worn condition the profiles maintain their form and are not subject to any further change. The worn profiles are characterized by good mutual conformity and thus by little increase in wear. The worn profile of tires results in a shortening of the wave length of the periodical wheel set motions (hunting) in the track clearance. It was concluded that to wear new profiles of rail heads and tires should be adapted as much as possible to the worn profile. The use of special wheel tire profiles promise no lasting influence on the riding quality of vehicles. Therefore other design measures on the vehicles should be preferred to control the hunting motion.
