摘要
高温超导(HTS)磁悬浮列车是下一代新型磁悬浮交通工具的备选方案之一。非接触轮轨系统使得轨道道岔面临诸多问题。给出了一种单倾角永磁体结构的新型机械永磁道岔结构。在使用单倾角永磁体装配永磁道岔时,两相邻永磁体之间的楔形缝隙用于调整永磁轨道在水平面上的曲率,以适应磁悬浮车变道目的。成功推导出了单倾角永磁体的几何尺寸、倾角大小和永磁道岔最小转弯半径之间的关系数学表达式并通过仿真计算进行了初步验证。计算结果表明,当永磁道岔换轨时,这种微小的差别不足于影响高温超导磁悬浮车的运行稳定性。
High temperature superconducting （HTS） magnetic levitation vehicles are one of the next generation high level Magnetic levitation （Maglev） transportation systems. Non - contact wheel - rail system makes the turnout system face many difficulties. In the paper, a novel mechanical permanent magnetic guideway （PMG） turnout system is proposed utilizing a single inclination permanent magnet （PM） for PMG turnout. To assemble the PMG turnout with the proposed single inclination PMs, the wedge shape air gap between two fixed PMs is used to adjust the PMG body bending in the horizontal plane for Maglev vehicle guideway switching purposes. The relationship of the geometric dimensions of the single inclination PM and its inclination angle and the minus turning radius of the PMG turnout is successfully derived. The calculation results show that it may not influence the HTS Maglev vehicles running stability during the PMG switching operation.
