针对空间旋转目标电磁消旋技术,本文提出一种计算空间旋转目标消旋力矩的新方法。首先,介绍了电磁消旋的常用计算方法；然后,介绍了能量守恒法的基本思想,从系统能量守恒的角度出发,从整体考虑电磁消旋过程中各物理场之间的相互作用,提出了一种基于能量守恒的消旋力矩计算方法,并通过球壳模型消旋力矩的计算过程对能量守恒法进行阐述。最后,进行了地面消旋实验,对比了实验结果和有限元法、电磁张量法、能量守恒法的计算结果。实验及仿真结果表明,本文提出的基于能量守恒的空间旋转目标消旋力矩计算方法有效。

For the electromagnetic-eddy current de-spinning technology of space rotating targets, a new method for calculating the damping torque of space rotating targets is proposed in this paper. Firstly, the common calculation methods of electromagnetic-eddy current de-spinning are introduced; Then, the basic idea of energy conservation method is introduced. From the perspective of system energy conservation, considering the interaction between various physical fields in the process of electromagnetic-eddy current de-spinning as a whole, a damping torque calculation method based on energy conservation is proposed. Through the calculation process of damping torque of spherical shell model, the energy conservation method is expounded. Finally, the ground damping experiment is carried out, and the experimental results are compared with the calculation results of finite element method, electromagnetic tensor method and energy conservation method. The experimental and simulation results show that the method proposed in this paper based on energy conservation is effective.
