Ground surface high speed superconductor magnetic levitation sled test device

Abstract

The invention discloses a ground high-speed superconducting magnetic suspension sleigh test device and belongs to the high-speed test device technical field. The invention provides a technical proposal of the ground high-speed sleigh test device with low energy consumption, high security and reliability as well as high efficiency. The test device comprises a permanent magnetic guide track and a foundation, a high temperature superconductor, a thin-wall liquid nitrogen low-temperature retainer, a magnetic suspension sleigh, a propulsion device for double-edged high-temperature superconductor linear synchronous motor, an electric energy supply and power regulation system and so on. The highly self-stabilizing magnetic suspension system is realized by the action of the electromagnetic force of the bulk high-temperature superconductor and the high electric field permanent magnetic guide track, the high propulsion is produced by the action of the secondary of a high-temperature superconductor linear motor positioned at the bottom of the magnetic suspension sleigh and the three-phase winding of a double-sided linear motor positioned at the foundation, such proposal contributes to the minimized quality design of the magnetic suspension sleigh test device and the realization of larger speed range. The invention is expected to realize the ground acceleration of 0 to 10g and the ground operation linear speed of more than 1000m / s, and is mainly used in technical problem research of weapon systems such as aviation, spaceflight and so on, as well as civil high-tech products during the operation with high speed and high acceleration.

Description

technical field [0001] The invention relates to the technical field of high-speed testing devices. Background technique [0002] The development of national defense weapons and equipment such as aviation and aerospace, as well as civilian high-tech products, needs to focus on solving a series of technical problems that they may encounter during high-speed, high-acceleration operations, such as missile inertial guidance and control systems, crew ejection lifesaving, air Power, parachute, aviation physiology, high overload, propulsion system, rain erosion, sand erosion, collision, fuze and explosion shock, etc. The research and solution of these technologies need strong test facilities as a support. The current test measures mainly include various types of wind tunnels, flight tests and rocket sled test slides. Among them, the rocket sled test slide rail is a large-scale, high-precision ground dynamic simulation test equipment developed in the second half of the 20th century....

AI Technical Summary

Problems solved by technology

However, the EMS system has problems such as complex control system and small suspension height, so it is difficult to apply to higher-speed ground operation, while the EDS low-temperature superconducting suspension system requires high-cost liquid helium cryogenic cooling system technology, and its operation stability is average. Therefore the application is also limited
