A positioning system and method for a maglev train, the positioning system comprising an onboard magnet mounted at the bottom of a train, two grating arrays laid on train tracks side by side in the traveling direction of the train, an optical pulse generation module and a data processing module. The data processing module performs first-stage train positioning according to drift conditions of the center wavelengths of the marking gratings, performs second-stage train positioning according to drift conditions of the center wavelengths of the first grating array, and performs third-stage train positioning according to drift conditions of the central wavelengths of the second grating array, so as to determine the track positions where the train arrives step by step.

Disclosed are an electromagnetic transverse active damping system, and a control method and apparatus therefor. The electromagnetic transverse active damping system comprises an electromagnet controller, wherein the electromagnet controller can determine a value of a damper target gap for an electromagnet active damper according to acquired train transverse acceleration, train position information and train speed, and control the action of the electromagnet active damper according to the determined value of the damper target gap; and electrical control is employed during the control of the electromagnet active damper by the electromagnet controller.

An inserted connection member for a train connector includes an insertion needle, an insulator, a disconnection preventing pad and an extrusion block. The insulator is sequentially provided with a positioning hole and an inserted connection hole in an axial direction. The insertion needle includes a line connecting segment, a positioning segment and an inserted connection segment which are connected sequentially, the line connecting segment and the positioning segment are arranged in the positioning hole. The disconnection preventing pad and the extrusion block are both sleeved on the line connecting segment, and the disconnection preventing pad includes a pad body and a boss arranged on the pad body. Thus, the insertion needle is ensured to maintain a stable contact even when the train is running at a high speed, and a disconnection preventing effect of the insertion needle is achieved.
