摘　　要：弹射器设计时在提高弹射性能的同时需降低工作产生的冲击,为满足此需求,针对一种典型弹射器,使用不同类型的火药为主装药,通过理论分析、数值仿真和发火试验,研究了不同类型主装药对弹射性能的影响。结果表明:根据弹射器的工作时间需求,选用合适的主装药能够提高火药的利用率,减少火药的装药量,提高产品的弹射性能。本研究为弹射器结构设计的优化和主装药的选型提供参考。To improve the ejection performance and reduce the impact when the ejector is designed,for some typical ejector with two different types of main charge,the effects of main charge on the ejection performance were studied,based on the theoretical analysis,numerical simulation and firing test.Numerical simulation and experimental results show that aimed to the function time requirement,selecting the suitable main charge can improve the utilization ratio of main charge,reduce the main charge mass and improve the ejection performance.The study can provide a reference for the optimization of the ejector structure design and the selection of the main charge.
