The invention relates to the field of aerospace, and particularly relates to a Lorentz force suspension method based on an artificial magnetic field, which is suitable for a suspension observation task of utilizing an electrified spacecraft on an earth high orbit. According to the method, an artificial magnetic field direction corresponding to any suspension position is obtained through analyticalexpression between a balance point position coordinate of a motion equation and the artificial magnetic field direction and introduction of an appropriate dimension to perform non-dimensionalizationon the balance point position equation, and a magnitude of a current required in a superconducting coil in the required artificial magnetic field direction is given. In the invention, only the currentin the three orthogonal superconducting coils on a main satellite needs to be adjusted so that any artificial magnetic field direction can be obtained and a required suspension task located at a balance point can be achieved; by changing an electric quantity of a slave satellite, the suspension position can be further adjusted; and an extra chemical fuel does not need to be consumed, and the method has an application prospect in a close-range suspension space observation task.
本发明涉及航空航天领域,特别涉及一种基于人工磁场的洛伦兹力悬浮方法,适用于地球高轨上利用带电航天器的悬浮观测任务。本发明通过运动方程的平衡点位置坐标与人工磁场方向之间的解析表达式,以及引入合适的量纲对平衡点位置方程无量纲化,进而得到任意悬浮位置对应的人工磁场方向,并给出了所需人工磁场方向下超导线圈中需要的电流大小。本发明只需调整主星上三个正交的超导线圈中的电流大小,就能得到任意的人工磁场的方向,就能实现所需的位于平衡点的悬浮任务,还可以通过改变从星上的带电量进一步调节悬浮位置,无需消耗额外的化学燃料,在近距离悬浮的空间观测任务中具有应用前景。
