Magnetic field characteristics analysis and optimization design of 30 cm xenon ion thruster
摘要
Abstract
The magnetic field design directly influences the stability and the in-orbit life of the discharge chamber . Aiming at the complexity of the 30 cm xenon ion thruster magnetic field design in variety of operating modes , the magnetic circuit characteristics was analyzed during the conversion between the electromagnet and permanent magnet . And the key parameters of the permanent magnet were optimized . The magnetic circuit model of the 30 cm xenon ion thruster was established , combined with the finite element method , the effectiveness and feasiblity of this method was validated by compared with the job site data . Based on this model , the key parameters of the permanent magnet which could produce requested magnetic induction intensity were obtained . Then the key parameters of the permanent magnet were optimized by using multiobjective particle swarm optimization (MPSO) algorithm , with the goal of the minimum anode shock voltage , accelerator grid current , decelerator grid current and magnetic circuit system weight system , and the relevant optimal result of magnetic circuit configuration for 30 cm xenon ion thruster was observed . Above research will certainly provide a method for the design and optimization of the ion thruster .关键词
