摘要
电磁发射系统中的电枢结构及特性参数对发射性能有重要影响。为了探讨复合电枢的动态特性及影响因素,基于麦克斯韦方程组及电磁场理论,推导出嵌入式和半嵌入式复合电枢动态发射耦合数学模型,分析储能电容器的容量及初始工作电压、驱动线圈的匝数、复合电枢结构参数等因素对加速性能的影响,仿真计算复合电枢的结构参数a、c、d对发射性能影响。结果表明:储能电容器的初始工作电压和电容越高,复合电枢发射效率越高;同步感应线圈炮中驱动线圈匝数也对复合电枢发射性能产生影响,随着匝数增加,发射效率并非一直升高;参数中a、c对发射性能影响很小,而参数d对发射性能影响很大。所提出的数学模型和分析结果可为复合电枢的设计提供理论基础和数据参考。
The armature structure and characteristic parameters in electromagnetic launch systems have a significant impact on the launch performance.In order to explore the dynamic characteristics and influencing factors of composite armatures,based on Maxwell s equations and electromagnetic field theory,a mathematical model of dynamic emission coupling between embedded and semi embedded composite armatures was derived.The influence of factors such as the capacity and initial working voltage of energy storage capacitors,the number of turns of driving coils,and the structural parameters of composite armatures on acceleration performance were analyzed and studied.The influence of structural parameters a,c,and d of composite armatures on emission performance was calculated.The results show that the higher the initial working voltage and capacitance of the energy storage capacitor,the higher the emission efficiency of the composite armature.The number of turns of the driving coil in the synchronous induction coil gun also affects the firing performance of the composite armature.As the number of turns increases,the firing efficiency does not always increase.The parameters a and c have little impact on the emission performance,while parameter d has a significant impact on the emission performance.The proposed mathematical model and analysis results can provide a theoretical basis and data reference for the design of composite armatures.
