摘要 为了研究电磁轨道炮结构设计参数与电枢出口速度之间的相关性,建立了电磁轨道炮电枢出口速度影响因素的指标体系,采用灰熵关联法,分析了电容、电感、电阻、电枢质量、轨道有效长度、放电电压对某口径电磁轨道炮电枢出口速度散布特性影响的显著程度.结果表明,放电电压、电容是影响电磁轨道炮精度的主要因素,电枢质量对电磁轨道炮精度影响最小,这为提高电磁发射系统的优化设计提供了科学依据. In order to study the relationship between the design parameters of electromagnetic railgun(EMG)and the velocity of armature,the index system of factors affecting the velocity of armature was built.By using grey relation entropy method,the significance of factors influencing the scattering of armature ' s muzzle velocity,including capacitance,inductance,resistance,armature ' s mass,effective length of railgun and charge voltage,was analyzed.The result shows that the main factors affecting the accuracy of EMG are discharge voltage and capacitance,and the effect of armature ' s mass on the accuracy of EMG is the smallest.The result offers scientific evidence for optimization design of EMG system.
