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 synchronous control method of a traction motor in an idling state of high-speed train wheels. Background technique [0002] High-speed trains are usually composed of multiple high-speed train carriages, each of which is equipped with a bogie at each end. Each bogie is equipped with two wheel sets, and each wheel set has two wheels. There is a bogie between the two bogies. Axle connection. The traction motor of the high-speed train is installed on the bogie under the carriage of the high-speed train. The shaft of the traction motor is connected to the axle of the bogie through a transmission. Usually, a traction motor is connected to the axle of a wheel set, and the traction motor torque is output to the axle through the transmission. The wheels are driven to rotate, and the single-carriage carriage has 4 wheel sets and 4 traction motors corresponding ...
