Embodiment Construction

[0039]The formation and development of rail corrugation is a cyclic process in which the dynamic behavior of the vehicle track interacts with corrugation, that is, when the vehicle passes through an irregular (curved) track, the vehicle and the track vibrate, resulting in uneven wear of the rail contact surface And plastic deformation, when the vehicle passes next time, the irregularities of the track and the accumulated uneven wear and plastic deformation of the rail contact surface will aggravate the vibration of the vehicle track, which will accelerate the uneven wear of the rail and increase the cumulative amount of plastic deformation. After repeated cycles, it leads to the formation of wavy wear on the contact surface of the rail. The interaction between wheel and rail is very complex, which includes dynamic action, wheel-rail contact action, friction action and the mechanism of their mutual interaction. According to an analysis, the rail wave wear is caused by the quasi-...

Abstract

The invention discloses a method for reducing the undulatory wear of steel rails. The steel rails are supported by sleepers and fixed to the sleepers through fasteners in fastened and pressed modes. Tracks of the steel rails guide wheels, and the steel rails and the wheels interact with each other to form a wheel rail system. According to the method for reducing the undulatory wear of the steel rails, the wheel rail flexibility difference and steel rail vibration, particularly in the wheel rail system transverse direction, are reduced. Through the method for reducing the undulatory wear of thesteel rails, vibration noise can be reduced, the undulatory wear of the steel rails is reduced, the wheel rail relation is improved accordingly, wheel rail vibration and noise are reduced, the service lives of the steel rails and the wheels are prolonged, the effectiveness of the track fasteners is improved, and the travelling safety is improved finally.

Description

technical field [0001] The invention relates to the technical field of railway track protection, in particular to a method for reducing rail wave abrasion. Background technique [0002] The abnormal wavy wear of rails caused by urban rail transit not only directly causes severe vibration and noise environmental problems of the rails and the environment, but also deteriorates the dynamic stability of the wheels and rails, leading to component failures that endanger driving safety, and greatly reduces the service life and increase of rails and wheels. The daily maintenance workload is reduced, and it also directly affects the efficiency of rail transit transportation. [0003] The formation and development mechanism of rail wave wear is very complicated. Since the 1970s, a large number of scholars and researchers at home and abroad have been engaged in research in this area for a long time, seeking the law of the generation mechanism and development of wave wear and the preven...
