大型磁屏蔽室设计与优化的研究

Study on Design and Optimization of Large Magnetic Shielding Chamber

大型磁屏蔽室主要目的是屏蔽地磁场以及磁干扰,为精密测量仪器标定、地磁导航实物仿真等提供一个“零”磁环境,因大型磁屏蔽室设计过程复杂,影响因素较多,从而理论计算与实际性能指标存在较大误差,因此有必要对大型磁屏蔽室的设计与优化进行研究,不仅对大型磁屏蔽室进行了仿真设计,且对关键参数以及外围影响因素进行优化。

The main purpose of large magnetic shielding room is to shield the geomagnetic field and magnetic interference,and provide a"zero"magnetic environment for calibration of precision measuring instruments and physical simulation of geomagnetic navigation,etc.Due to the complex design process of large magnetic shielding room and many influencing factors,there is a large deviation between theoretical design and actual performance indicators.Therefore,it is necessary to study the design and optimization of large magnetic shielding room.This paper not only simulates and designs the large magnetic shielding chamber,but also optimizes the key parameters and peripheral influencing factors.
