基于蚁群算法的同步感应线圈炮结构参数优化

摘要

能量转换效率一直是制约同步感应线圈炮(SICG)工程应用的重要因素.对于SICG系统,任何机电参数的改变都会直接或者间接地影响系统能量转换效率.为了提高SICG系统的能量转换效率,建立了SICG的机电模型,以驱动线圈的结构参数、电枢结构参数以及两者的轴向中心距为变量,以能量转换效率为目标函数,采用蚁群算法对60 mm口径的SICG系统进行了优化研究.研究结果表明,优化后系统能量转换效率从5.32％提高到15.2％.为了验证优化结果,搭建了SICG实验装置并进行了效率验证实验,优化结果得到了有效验证.%Energy conversion efficiency of synchronous induction coil gun is an important limiting factor for its development. Its any electromagnetic parameter change can directly or indirectly affect the electrical-to-kinetic energy conversion efficiency. In order to improve the energy conversion efficiency, an electromechanical model was built first. Then, as an example, an induction coil gun with caliber of 60 mm was optimized by using ant colony optimization algorithm. The electrical-to-kinetic energy conversion efficiency was increased from 5. 32% to 15. 2% . In order to validate the optimization results, an experiment was carried out in a single stage synchronous induction coil gun, and the results show that the optimization is effectively.
