  • 摘要:

    地磁导航半实物仿真是地磁导航从理论走向工程应用的关键环节,而地磁场环境仿真技术是地磁导航由计算机仿真过渡到半实物仿真的桥梁。针对地磁场环境仿真系统中磁屏蔽装置与其内部磁场模拟器的耦合问题,采用仿真分析与实验验证相结合的方法,利用Ansoft Maxwell仿真软件设计仿真实验对二者的耦合关系进行了探索性研究,并基于小型地磁场环境仿真系统对仿真得到的结论进行了实验验证。仿真和实验结果均表明:磁场模拟器在大电流强磁场的工作情况下会对磁屏蔽装置造成严重的磁化,进而会影响其屏蔽效果;磁屏蔽装置不会影响磁场模拟器的线性度和均匀性,但是会增大轴线中心点附近的磁场值;磁屏蔽装置会使磁场模拟器的电感增大,从而使实时性变差。研究结论可以为地磁场环境仿真系统的设计提供理论依据。
