针对电磁弹射装置激励和发射过程中产生的感应脉冲强磁场对周边电子设备造成的电磁干扰(EMI)威胁特征，基于有限积分技术(FIT)对弹射装置内磁场环境进行仿真分析，并对发射器结构开展磁场屏蔽特性设计研究。以某装置应用为例，在5 kHz以下低频段，内部磁场值可达10 T，通过多层梯度复合磁屏蔽结构设计，实现磁场屏蔽效能达40 dB，满足了该系统磁防护设计要求。

Abstract
Wuhan National High Magnetic Field Center, Huazhong University of Science and Technology, Wuhan, 430074, China
Wuhan National High Magnetic Field Center (WHMFC) at Huazhong University of Science and Technology is one of the top-class research centers in the world, which can offer pulsed fields up to 90.6 T with different field waveforms for scientific research and has passed the final evaluation of the Chinese government in 2014. This paper will give a brief introduction of the facility and the development status of pulsed magnetic fields research at WHMFC. In addition, it will describe the application development of pulsed magnetic fields in both scientific and industrial research.
