Experimental analysis on dynamic performance of scale-model high temperature superconductor bulk magnetic levitation and propulsion system

The paper focus on magnetic levitation and propulsion technology of a scale-model superconductor system with high temperature superconductor (HTS) bulks over a 7-meter NdFeB guideway for concept launch assistance. The vibration experiment is done to investigate the dynamic characteristics such as the resonance frequency, suspension quality and suspension stiffness. The purpose is to evaluate the influence degree under a certain vibration condition. The dynamic experimental acceleration system platform and testing system are established to investigate the movement performance. Experimental design is to provide the warranty of stabilization and show the idea of improving the stability of the acceleration system. The acceleration experiment further confirms the security of the launch assistance suspension system which also gives a reference and evaluation method of the stability and security in the aerodynamic and separation system design.
