| 摘 要： | 对轨道型固体电枢电磁发射的电磁过程进行了研究,建立了基于麦克斯韦准静态A-Φ场方程的3维静枢电磁发射数值模型。利用ANSYS有限元电磁模块结合发射装置的实测参数,对电枢在静枢模型下的电磁发射进行了模拟。计算结果表明:馈入相同电流加载波形时,流经C型电枢的电流密度、磁通量以及电磁发射过程中所受电磁力,在不同时刻的内部分布、峰值和大小均与文献计算结果相符。

| Abstract: | This paper studies the 3D electromagnetic behavior of solid armature in rail electromagnetic launcher(EML) using finite-element(FE) software ANSYS.A simple quasi-static model for EML,with A-formulation of Maxwell's equations,is discussed to simulate the three-dimension C-shaped armature.Good agreement to the published simulation data is obtained from EM code EMAP3D,including the current density distribution,magnetic field distribution and Lorentz force in the solid armature for different time.The results in... |
