高速磁浮轨道不平顺测试及分析 总被引：2，自引：0，他引：2
研究目的：提出高速磁浮轨道不平顺处理方法,分析不平顺特征,拟合形成轨道谱,为线路卒问维护提供参考。创新要点：实现了对高速磁浮轨道不平顺的提取,确定了轨道谱参数。研究方法：基于惯性基准法,运用数字信号处理方法实现对轨道不平顺的提取,采用最小二乘法拟合得剑定子向和导向面七参数轨道谱。重要结论：定子面和导向面分别在5-100m和10-100m波长范围内平顺性状态较好,由功能件安装等引起的1-5m和1—10m波长范围内的偏差应严格控制。 相似文献

A new electromagnetic suspension model using a combination of high temperature superconductors (HTS) and copper conductors is proposed in this paper. A feasibility study showed that the magnets of our model can generate the 250 kg vertical suspension force. Three dimensional FEM and Design Sensitivity Analysis using the levitation gap length and cross sectional dimensions of the HTS magnets as design parameters were conducted to obtain the optimal shape of the cross section and the configuration of the HTS magnet. It was found that the gap length when optimized HTS magnet was used was much larger than that when copper conductor magnet was used, while the HTS coil volume was minimum, and the perpendicular field along the outer surface of the HTS coil was less than 0.12 T. 相似文献

The dynamic interaction between maglev vehicle and three-span continuous guideway is discussed. With the consideration of control system, the dynamic interaction model has been developed. Numerical simulation has been performed to study dynamic characteristics of the guideway. The results show that bending rigidity, vehicle speed, span ratio and primary frequency all have important influences on the dynamic characteristics of the guideway and there is no distinct trend towards resonance vibration when fl/（v/l） equals 1.0. The definite way is to control impact coefficient and acceleration of the guideway. The conclusions can serve the design of high-speed maglev three-span continuous guideway. 相似文献
