Abstract

The invention provides a rail train wheel-rail adhesion control method, comprising: inputting a creep signal to the electromagnetic torque signal of the traction motor; detecting the speed signal of the traction motor and the torque current signal of the traction motor; obtaining the phase of the speed signal The phase of the torque current signal; the phase of the speed signal and the phase of the torque current signal are input to the linear controller, and the linear controller calculates the phase difference between the phase of the speed signal and the phase of the torque current signal; the linear controller The phase difference between the control speed signal and the torque current signal is equal to the preset value, which can detect and control the traction motor in real time to avoid idling and sliding between the wheels and rails.

Description

technical field [0001] The invention relates to the technical field of rail train manufacturing, in particular to a method for controlling wheel-rail adhesion of rail trains. Background technique [0002] The power of the rail train is provided by the power bogie. The power bogie includes a traction motor and a wheel set connected to the traction motor. The rail train is driven to run on the rails; when the train is in the traction condition, if the train is in the braking condition, if the braking force of the train is greater than the maximum adhesion force that the wheel and rail can provide, sliding will occur. When the torque output by the traction motor reaches a certain value, it will cause the wheelset to idling on the rail, and idling phenomenon will occur, and idling and sliding will easily scratch the wheelset or rail; therefore, how to control the torque of the traction motor has become a research hotspot . [0003] In the prior art, the linear speeds of the fo...
