摘要
为高效研究电磁发射用脉冲功率电源放电性能,为电磁发射提供技术支持,降低研发成本,电磁发射过程的相关建模与仿真工作需要重点研究。对弹丸在轨道中实际运动物理过程建立数学模型,对脉冲功率电源建立电路模型,采用联合两种模型的方法对脉冲功率电源放电系统进行研究,提出一种基于发射过程多物理现象的脉冲功率电源放电系统仿真模型。通过实验验证了提出方法的有效性,为后续脉冲功率电源放电研究提供了依据。
In order to effectively study the discharge performance of pulsed power supply for electromagnetic launch,provide technical support for electromagnetic launch and reduce the cost of research and development,the related modeling and simulation work of electromagnetic launch process needs to be studied.A mathematical model for the actual physical process of the projectile was established,a circuit model of the pulsed power source was set up,and the discharge system of pulsed power supply was studied by using the method of combination of these two models.Furthermore,the simulation model of pulsed power supply discharge system based on the multi physical phenomena in transmit process was proposed.The effectiveness of the proposed method was verified by experiments,which lays a foundation for the discharge research of pulsed power supply.
