Based on the flux pinning characteristics of non-ideal type Ⅱ superconductors YBa₂Cu₃O_7-x, high temperature superconducting (HTS) pining magnetic levitation (maglev) is a self-stable levitation system with the merits of simple and reliable principle, friendly environment, etc. However, this maglev system is plagued by its prominent weak damping properties, which are unfavorable to the safety and comfort of the vehicle in operation under different external excitation. Therefore, the secondary suspension system should be added to this rail vehicle to enhance its damping property and its dynamic performance. This paper proposed a semi-active secondary suspension designed for the HTS pining maglev system. And this semi-active suspension can adjust the damping coefficient adaptively according to the motion state of the maglev vehicle. Moreover, an HTS pining maglev test vehicle "super maglev" is used to verify its effectiveness. Compared with the experimental and simulation results of a passive secondary suspension system, the dynamic performance of the maglev system with a semi-active suspension system is greatly improved. Furthermore, this semi-active suspension was applied to an engineering HTS pining maglev system through simulations. Eventually, through comparative analysis, the results show that the semi-active control damper controlled by PD can not only ensure the safety of passengers but also significantly improve the running stability of the vehicle, which has practical and economic advantages.

基于非理想Ⅱ型超导体YBa ₂ Cu ₃ O _{7-x的磁通钉扎特性}, 高温超导 (HTS) 钉扎磁悬浮 (maglev) 是一种自稳定的悬浮系统, 具有原理简单可靠、环境友好等优点。然而, 这种磁悬浮系统存在突出的弱阻尼特性, 即不利于车辆在不同外部激励下运行的安全性和舒适性。因此，应在该轨道车辆中增加二次悬挂系统，以增强其阻尼性能和动态性能。本文提出了一种专为HTS pining磁悬浮系统设计的半主动二次悬架。并且这种半主动悬架可以根据磁悬浮车辆的运动状态自适应调整阻尼系数。此外，还使用了HTS pining磁悬浮试验车“超级磁悬浮”来验证其有效性。与被动二次悬挂系统的实验和仿真结果相比，半主动悬挂系统的磁悬浮系统的动态性能有了很大的提高。此外，通过仿真将该半主动悬架应用于工程高温超导磁悬浮系统。最终通过对比分析，结果表明，PD控制的半主动控制阻尼器既能保证乘客的安全，又能显着提高车辆的行驶稳定性，具有实用性和经济性优势。通过仿真将该半主动悬架应用于工程 HTS 钉扎磁悬浮系统。最终通过对比分析，结果表明，PD控制的半主动控制阻尼器既能保证乘客的安全，又能显着提高车辆的行驶稳定性，具有实用性和经济性优势。通过仿真将该半主动悬架应用于工程 HTS 钉扎磁悬浮系统。最终通过对比分析，结果表明，PD控制的半主动控制阻尼器既能保证乘客的安全，又能显着提高车辆的行驶稳定性，具有实用性和经济性优势。
