Calculation method of damping torque of space rotating targets based on energy conservation
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 is proposed.Through the calculation process of damping torque of a spherical shell model,the energy conservation method is expounded.Finally,a ground damping experiment is carried out,and the experimental results are compared with the results of the 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.
