摘要

为了实现高效、精确的电磁发射一体化弹丸效果,深入理解一体化弹丸在电磁场中的动态响应和运动特性,通过采用基于COMSOL的电磁场仿真模拟方法,结合理论推导和数值计算,对电磁发射一体化弹丸的动力学行为进行了系统的研究.建立了有限元模型,对弹丸在电磁场中的受力情况进行了描述和分析;利用COMSOL软件进行仿真,得到了弹丸在电磁发射过程中的速度和位置等关键参数;并得到相关的磁场特性.通过对仿真结果进行分析,深入了解弹丸在电磁场中的运动轨迹和磁场特性,进一步揭示其运动特性和响应机制,为电磁发射技术的进一步发展提供重要的参考和指导.

Abstract

In order to achieve efficient and accurate electromagnetic launching of integrated projec-tiles,a comprehensive study was conducted to further understand the dynamic response and motion characteristics of integrated projectiles in electromagnetic fields.This study employed a simulation ap-proach based on COMSOL,combining theoretical derivation and numerical calculation,to investigate the dynamic behavior of electromagnetic launched integrated projectiles.Firstly,a finite element model was established to describe and analyze the forces acting on the projectile in the electromagnetic field.Subsequently,the COMSOL software was utilized for simulation to obtain key parameters such as velo-city and position of the projectile during the electromagnetic launching process,as well as the associa-ted magnetic field characteristics.By analyzing the simulation results,a thorough understanding of the projectile's motion trajectory and magnetic field characteristics in the electromagnetic field was achieved,thereby revealing its motion properties and response mechanisms.This research provides sig-nificant reference and guidance for further development of electromagnetic launching technology.
