在电磁拦截系统动能优化问题的研究中,拦截弹的电磁发射过程,是一个涉及多物理场的复杂动态过程,求解困难。传统分析方法存在电磁场分析与电路分析相互孤立的问题。为提高动力性能,提出场路耦合分析方法,利用Maxwell 2D与Simplore的协同仿真对拦截弹的电磁发射过程进行了仿真研究,得到了发射过程中放电回路的电流波形、发射装置的磁场和涡流分布,以及拦截弹所受电磁力、拦截弹速度和位移随时间的变化规律。并进行了拦截弹发射实验,实验结果与仿真数据的一致性表明所建立的场路耦合模型是正确的。
In the research of kinetic energy optimization of the electromagnetic interception system, interception of the electromagnetic emission process of the projectile is a complex and dynamic process involving multiple physical fields, which is difficult to solve. The traditional analysis method has the problem that the electromagnetic field analysis and the circuit analysis are isolated from each other. In order to improve the dynamic performance, a method of field-circuit coupling analysis is proposed. The electromagnetic launch process of the interceptor is studied by using the co-simulation of Maxwell 2D and Simplore. The current waveform, the magnetic field and the eddy current distribution of the discharge circuit are obtained. , As well as the electromagnetic force intercepted by the projectile intercepting the variation of the projectile’s velocity and displacement with time. The interception missile launching experiment was carried out. The consistency between the experimental results and the simulation data shows that the established coupling model of the field and road is correct.
