Background

According to the optimal wheel-rail shape matching scheme of the wheel tread and the steel rail generating relative motion according to the wheel-rail dynamics, the wheel-rail concentrated abrasion is matched with the optimal steel rail top shape based on the best wheel contour shape. Thus, the wheel tread profile can be divided into concentrated areas (generally, areas of adhesive contact with the centerline of the wheel tread) where wear is frequent, and areas outside the concentrated areas are areas of non-concentrated wear. Under the condition that the hard wheels on the rail are soft, the wheels with smooth surfaces and the steel rail are intensively worn away from each other, and the wear is a basic reason for generating unbalanced wear of the tread of the conventional wheel.

Concentrated wear on the wheel tread is a significant source of maintenance for the vehicle wheel. The wheel tread concentrated abrasion recovery method is to recover the original wheel contour shape by cutting the wheel contour of the tread non-working area and turning the wheel contour, which not only needs maintenance time, but also needs to consume a certain amount of wheel, although a wheel brake or tread cleaning device is also a method for recovering the wheel tread contour shape, the method has the disadvantages of accelerating the wheel consumption speed, generating hard spots on the wheel, increasing the consumption of wheel abrasive materials, correspondingly increasing the maintenance cost, and increasing the maintenance task workload and safety risk, so the method provides a functional steel rail with balanced abrasion of the tread for the situation.
