| 摘 要： | 磁力矩器是卫星上磁性较大的部件之一,局部的强磁场是影响卫星周围带电粒子分布的主要原因。为了定量分析磁力矩器与等离子体相互作用,文章基于磁场与运动粒子的耦合模型,利用有限元数值分析软件仿真了典型轨道航天器上磁力矩器工作时周围带电粒子入射轨迹变化及电荷(粒子数)分布。结果表明,受磁场作用,带电粒子在接近磁力矩器本体时会发生偏转,且偏转幅度随电子能量降低而增大;由磁场引起的这种偏转效应导致带电粒子不均匀入射到卫星内。

| Abstract: | The magnetorquer is an important component to provide relatively intense magnetic fields in a spacecraft. The produced intense magnetic fields play an important role in the distribution of ambient charged particles. In order to make a quantitative analysis of the interaction between the magnetorquer and the ambient plasma, the finite element method is used to simulate the charged particle traces when they fly towards the magnetorquer based on the coupling model of moving electrons in the magnetic field. From the simulation data, we can see notable deflections in the traces of the incoming charged particles when they pass by the magnetorquer, and this kind of deflection is increased as the incoming particle energy decreases. Because of the deflection, there exists an asymmetric distribution of the charged particles injected to a satellite. |
