Synchronous control method of traction motors under idling condition of high-speed train wheels

Abstract

The invention provides a synchronous control method of traction motors under idling condition of high-speed train wheels. The synchronous control method has the characteristics that a central processing module and a plurality of traction control modules are comprised; the synchronous control method comprises the steps that target speed parameters are given; current speed parameters of the tractionmotors are obtained; currentsynchronous control values of traction motors are obtained; and rotary speeds of the traction motors are adjusted and driven according to synchronous control value signals. According to the synchronous control method, in the process of speeding up the high-speed train, the rotary speeds of the traction motors are controlled synchronously, the speed mutation of a idlingmotor can be rapidly lowered, the damage brought by the speed mutation can be reduced, and the cost of high-speed train operation and maintenance, and safety accidents can be reduced.

Description

technical field [0001] The invention relates to the technical field of automatic control of urban rail trains, in particular to a method for synchronous control of traction motors in high-speed train wheel idling state. Background technique [0002] A high-speed train is usually composed of multiple carriages. Each carriage is equipped with a bogie at both ends. Each bogie is equipped with two wheel pairs. Each wheel pair has two wheels. The two bogies are connected by a Axle connection. The traction motor of a high-speed train is installed on the bogie under the carriage of the bullet train, and the shaft of the traction motor is connected to the axle of the bogie through a transmission. Usually, one traction motor is connected to the axle of a wheel set, and the torque of the traction motor is output to the axle through the transmission. The driving wheels rotate and run, and there are 4 wheel sets and 4 corresponding traction motors in a single train carriage. [0003] ...
