摘　　要：以永磁电动悬浮在航天磁悬浮助推、弹目交会实验等军事领域的实际应用为背景,基于直线型Halbach结构永磁电动悬浮技术设计了一个永磁电动悬浮实验平台,选择金属转盘作为永磁电动悬浮系统的轨道形式,并对直线型Halbach结构永磁体的几何形状进行了优化设计。最后,通过相关的静态特性实验测试,验证了永磁电动悬浮系统的基本特性,通过分析其与理论计算存在差异的原因,讨论了相应的补偿修正方法。另外,动态特性的测试得到了系统的欠阻尼特性。On the background of applications of permanet-magmet EDS in launch assistance suspension,missile-target encounter experimentation,a permanent magnet EDS platform based on PM Halbach structure EDS system technology was designed and constructed.A metallic disc was chosen to be the track,and the geometrical optimal design of the Halbach permanent magnets was performed.Finally,according to the corresponding static tests,the main characters of the permanent-magnet EDS system were validated.By ways of analyzing the cause of the discrepancy between tests and calculating values in theory,relevant error-correction methods were discussed.Besides,the underdamping characteristic was acquired from dynamic tests.
