Abstract以国际地磁参考场模型IGRF11为基础,推导出地球磁场梯度分布公式,并对近地空间磁场分布特点进行了分析。由基本磁力学可知,带强磁体的航天器在地磁环境中不仅受到磁力矩作用,还将受到与地磁梯度相关的磁力的影响。根据地磁环境下的磁体受力机理,文章讨论了以弱磁力改变轨道倾角的方法,并通过数值仿真验证了其有效性。
Other AbstractBased on the 11th international geomagnetic reference field(IGRF11) model,the gradient distribution characteristics of the geomagnetic field in the near-Earth space are analyzed.From magnetics,it is known that the spacecraft with a strong magnet moment is not only affected by the magnetic moment,but also by a magnetic force related to the geomagnetic gradient.This paper discusses how to change the orbital inclination angle by the weak magnetic force,based on the force analysis for a magnet interaction with the geomagnetic field in the IGRF11 model.Numerical simulations are carried out to test the effectiveness of this idea.
