Pmg Optimization Design Of High Temperature Superconducting Maglev System

High-temperature superconducting permanent maglev system, take use of the interaction between the high-temperature superconductors and permanent magnets to achieve stable levitation, which represents a research and development direction of the world today.In practical applications, the high-temperature superconducting maglev train system has been widely used in research because of its high efficiency, low noise and other fine features. However, the running features of the train are affected not only by the the applied perturbation from outside but also superconductor’s inner characteristics.In the other hand the advantages and disadvantages of permanent track performance directly determines the comfort and safety of train operation. Based on this, the permanent magnetic guideway is under some comparative research and design verification.As follows:In the Chapter Ⅰ start from the two characteristics of the superconductor (Onnes effect and anti-magnetic), tells the story of a superconducting material is found and deepen the research process, to pave the way to the understanding of high-temperature superconducting maglev train system, and finally the overall framework of the thesisa brief introduction..In the Chapter Ⅱ,a brief introduction of the basic knowledge of the high-temperature superconducting maglev system is told, which also includes some of the effects of the suspension characteristics of high-temperature superconducting maglev system. Then the development of today’s domestic and foreign maglev train.In the chapter Ⅲ,the Ansoft-Maxswell engineering software is used to comparative study of the magnetic field distribution of a variety of different arrangement of permanent magnet in orbit, and find out that different specifications of different materials with different parameters for the specific impact of the permanent orbit above the magnetic induction, and design an optimal way the permanent magnetic guideway arrangement.In the next Chapter YBaCuO superconductor and sintered Nd-Fe-boron permanent magnets based on specific experimental model of high-temperature superconducting maglev train system, as well as simple quench time measuring device production principle and model.Chapter V based on the previously described herein, a new designed track suspension in a variety of circumstances the determination of the levitation force-displacement curve, while superconductor quench time under different conditions were tested to obtain the results and analysis.
