Abstract: As a control structure, the magnetic repulsion device is applied in the high-speed switch hydraulic operating mechanism. It must not only move quickly but also stop precisely. The repulsion disk is subjected to high impact loads, resulting in the phenomenon of fracture and damage. In this paper, the magnetic repulsion value of the engineering prototype was obtained through simulation. A super-elastic material was selected as the buffer, and impact dynamics simulation was carried out. A double-repulsion-disk structure was designed, which reduced the structural impact stress and satisfied the operation time of less than 2 milliseconds. This realized redundant design and improved the reliability of the high-speed switch hydraulic operating mechanism, which is of great significance for the safe operation of high-speed switches.
