摘要:

基于磁悬浮助推技术概念研究方案建立了一套悬浮加速缩比试验系统。从整体缩比模型振动试验出发,主要研究悬浮质量以及悬浮刚度对整体系统动态性能的影响,并在进行缩比单元动态试验结论的基础上,建立试验模型的加速试验动态采集系统,对整体模型进行运行性能试验。在试验基础上提出了提高磁悬浮推进系统运行稳定性的依据,并据此提出相应可行的解决方案设想。通过模型加速试验并采集试验数据定性分析磁浮系统的综合运动性能,以更好地评估系统稳定特性和品质,也为进一步研究磁悬浮助推发射的气动、分离系统稳定性和可靠性提供参考。

Abstract:

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.
