First of all, the performance requirements of the steady-state plasma thruster on the magnetic field are analyzed. Based on this, the engineering design principles and methods of the magnetic circuit system are introduced. Then, a large-scale finite element analysis software ANSYS is used to analyze the performance of a specific steady- Operating conditions of the magnetic field were calculated and obtained satisfactory results. Through the analysis of the results, the author got an intuitive and in-depth understanding of the phenomena and provided clues for the improved design of the specific thrusters. At the same time, it also confirmed the steady state plasma thruster magnetic circuit system computer with ANSYS software platform Numerical simulation of aided design feasibility and effectiveness.
