| 摘 要： | 为了满足低成本、高安全可靠的可重复使用航天运载器发展需要,磁悬浮助推发射技术以其高地面起飞速度,提供了一种可能的技术途径。设计和研究了一种永磁导轨与高温超导体作用形成的磁悬浮系统。通过建立磁悬浮单元准静态力测试系统,分析了块状高温超导体在永磁导轨上方不同位置作用的悬浮特性。然后建立高温超导磁悬浮缩比研究试验平台,其包括4个磁悬浮单元和7米双永磁导轨。通过测试和分析试验平台在不同场冷高度和载荷条件下的悬浮特性,得出低场冷高度有利于提高磁悬浮发射装置的横向稳定性。

| Abstract: | With the need for a low-cost,safe,reliable,and recoverable vehicle to get to space,magnetic launch assist(Maglifter) represents one possible strategy for achieving the vehicle with high ground take-off velocity.In this article,a permanent magnet guideway-high temperature superconductor(PMG-HTS) interaction magnetic levitation (Maglev) system was designed and investigated.A quasi-static force measuring setup was built to study the levitation properties of bulk HTSs above the different positions on the top surface of the PM guideway.Then a demo HTS Maglev test platform was constructed with 4 Maglev units and 2 PM tracks of 7m length.The levitation characteristics of the test platfrom were measured and analyzed at different field-cooled heights(FCH) or loading conditions.As a result,the low FCH was useful for increasing the lateral stability of the Maglifter. |
