Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0041] In the prior art, the suspension rated gap is generally set as a fixed value. Since the gap fluctuation increases with the increase of the speed, in order to avoid the suspension electromagnet from contacting the track when the gap fluctuation is too large, the suspension rated gap is usually set as If the value is larger, a larger levitation electromagnet current is required, and the electromagnet generates more heat, which requires good heat dissipatio...

Abstract

The invention discloses a maglev train suspension control method, system and device and a readable storage medium. The maglev train suspension control method comprises the following steps that a real-time suspension gap, a real-time speed and a real-time acceleration of a maglev train are obtained; according to a positive related functional relation between the real-time speed and a rated suspension gap, a present rated suspension gap corresponding to the present real-time speed is determined; and a suspension control current is determined corresponding to the present rated suspension gap, the present real-time acceleration and the present real-time suspension gap of the maglev train, and the suspension control current is applied to a suspension electromagnet. According to the method, the corresponding rated suspension gap is determined according to the real-time speed, and then the suspension control current to be applied to the suspension electromagnet is determined, so that a real suspension gap generated by the action of the suspension electromagnet at the real-time speed and the heat dissipation effect of the electromagnet achieve a good balance, and the contradiction between a suspension gap requirement and a suspension electromagnet heat dissipation requirement in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of rail transit vehicles, in particular to a levitation control method, system, device and readable storage medium of a maglev train. Background technique [0002] The maglev train is a new type of rail transportation with outstanding features such as low operating noise, strong climbing ability, small turning radius, high safety and reliability, low operation and maintenance costs, and low construction cost. It uses electromagnetic suction to suspend the car body above the track, and maintains a non-contact state between the train and the track, which overcomes the contact wear between the two and reduces the running resistance. The suspension control system is the actuator to realize the suspension of the vehicle. It changes the internal current of the suspension electromagnet according to the air gap between the suspension electromagnet and the track transmitted by the suspension sensor installed on the e...
