摘要

在常规弹的地磁导航系统中,载体磁场是影响磁传感器测量精度的主要干扰因素。为了准确地对这一干扰磁场加以消除或者补偿,文中对载体磁场中感应磁场的分布规律进行了仿真研究。文中采用磁标量法求解磁场,研究了常规弹的三维静态磁场仿真技术,使用有限元工具ANSYS仿真得到了弹体上各点磁感应强度的数值解,根据绘制的云图和数据变化曲线图,分析得到了匀强磁场中弹体内部以及沿弹壁轴向和横截面上感应磁场的变化规律。

Abstract

In the geomagnetic navigation system of a common projectile, the vehicle's magnetic field is a main factor affecting the measurement accuracy of geomagnetic sensor. In order to eliminate or compensate the interference, the distribution of vehicle's magnetic field needs to be studied. In this paper, the magnetic equation was solved with magnetic scalar method. Three-dimensional static magnetic field simulation technology was studied. Numerical solution of magnetic induction distribution in the projectile was obtained by the finite element tool of ANSYS. The change rule of magnetic induction in the projectile with an external uniform magnetic field was analyzed through the contour plot and data curve.

Key words： geomagnetic navigation; vehicle's magnetic field; magnetic scalar method; ANSYS; uniform magnetic field
