Abstract

The invention provides an electromagnetic lateral active vibration damping system and a control method and device thereof, By setting an electromagnet controller in the electromagnetic transverse active damping system, the electromagnet controller can determine the target clearance value of the electromagnet active damper according to the obtained transverse acceleration of the train, the positioninformation of the train and the train speed, and control the action of the electromagnet active damper according to the determined target clearance value of the electromagnet active damper. The electromagnet controller adopts the electric control mode to control the electromagnet active vibration absorber, which improves the response speed of the electromagnetic lateral active vibration absorbersystem, and makes the electromagnetic lateral active vibration absorber system operate in time at the position where the car of the high-speed train tilts or shakes.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an electromagnetic lateral active damping system and a control method and device thereof. Background technique [0002] At present, the speed of high-speed trains is getting faster and faster. For example, the maximum speed of the maglev train that is about to be put into use can reach 503 kilometers per hour. When traveling at such a high speed, if the track on which the high-speed train is running is uneven, or if the high-speed train needs to turn, the carriage of the high-speed train will roll or shake, which will reduce the experience of passengers on the train. [0003] In order to reduce the rolling or shaking of the carriage of the high-speed train during running, a lateral damping device can be installed on the bogie of the high-speed train, and when the high-speed train passes through potholes and uneven tracks or turns The torque device or elastic element controls th...
