摘要
提出外加磁场的等效试验方法,对电磁轨道发射装置实施永磁体、单级线圈、多级线圈3种外加磁场,进行金属材料与电磁能作用机理的理论研究和仿真分析。结果表明:永磁体不能满足等效条件,外加线圈方式能够等效电磁轨道发射磁场环境;当电流为30 kA,10匝线圈采用每层5匝线圈的双层排列方式时,能够取得数值较大且分布均匀的磁感应强度;采用多级结构的外加线圈增强型装置能够提高装置效率。
The equivalent test method of external magnetic field was proposed,and three external magnetic field methods of permanent magnet with single-stage coil and multi-stage coil were applied to the electromagnetic rail launch device.The mechanism of interaction between metal materials and electromagnetic energy was studied theoretically and analyzed by simulation.The results show that the permanent magnet cannot meet the equivalent condition,and the applied coil method can be equivalent to the electromagnetic rail launch magnetic field environment.When the current is 30 kA and the 10 coils are arranged in a double layer with 5 coils in each layer,and the magnetic induction intensity with large value and uniform distribution can be obtained.The multi-stage structure of the external coil enhanced device can improve the efficiency of the device.
