Abstract
Proposed are a synchronous braking control method and system for carriages of a train, that are related to the field of electrical control. The synchronous braking control system includes a main controller, an electric energy conversion controller, and a shunt. During actual braking, the main controller obtains a real-time speed and real-time mass of the train, and determines whether the real-time speed is greater than a set speed. If not, the train is directly braked in a mechanical friction braking mode. If yes, an exciting current of a synchronous brake in each of the carriages of the train is adjusted by adjusting an input voltage of the synchronous brake, and unit braking forces of the carriages are controlled equal by using the adjusted exciting current, thereby realizing synchronous constant deceleration braking of the carriages.
