Abstract

The invention discloses a method and device for determining the abrasion of a railway turnout steel rail, a storage medium and a processor. The method comprises the steps of determining a coupling dynamic simulation model of a vehicle turnout; according to the dynamic simulation model, conducting simulation to obtain wheel-rail contact parameters of the vehicle turnout; according to the contact parameters, obtained through simulation, of the vehicle turnout, conducting calculation to obtain an abrasion depth distribution result in a contact spot; obtaining abrasion rates of different sectionsaccordingly; obtaining step length information for iteration steps according to the abrasion rates of different sections of the steel rail, and calculating steel-rail cumulative abrasion of the iteration steps according to the abrasion rates of different sections and the step length information for the iteration steps; if the peak value of the steel-rail cumulative abrasion obtained in the iteration steps reaches the limit value, sending updating information, wherein the updating information is used for characterizing the need for updating the steel rail. The method and device for determiningthe abrasion of the railway turnout steel rail, the storage medium and the processor solve the problem that in the prior art, the abrasion of the turnout steel rail cannot be reasonably and accuratelypredicted.

Description

technical field [0001] The invention relates to the field of railway wear calculation, in particular to a method and device, a storage medium, and a processor for determining rail wear of a railway turnout. Background technique [0002] Turnout is the key railway equipment for locomotive vehicles to turn or cross the line. It has a complex structure and many components. During the operation of high-speed turnouts, the problem of wear of the switch rails is particularly common in the switch area. Wear will cause changes in the profile of the rail head and the relative position of the basic rails of the switch rails, and will directly affect the wheel-rail contact state and wheel load when the train passes the switch. The transitional situation will have a serious impact on the safety and stability of train operation. In addition, problems such as vibration and shock, plastic deformation, and peeling off blocks caused by poor contact will also seriously reduce the service lif...
