摘要: 针对狙击步枪手动击发对瞄准线的扰动以及响应速度慢等不足,提出一种新型嵌入握把内部的电动击发装置,分析其工作原理,建立电击发装置的参数化模型,并对该电击发装置进行了仿真分析与实验测试。结果表明:该电动击发装置能够实现发射机电控击发,其对瞄准线方位方向的扰动幅度降为手动击发的1/5,可有效降低击发对瞄准线的扰动,提高射击精度;响应时间约为35 ms,远快于手动击发速度,提高了狙击步枪击发的响应速度,有助于准确把握击发时机。

Abstract: A novel electric firing mechanism which is imbedded in the rifle grip is proposed for the disturbance to line-of-sight (LOS) and low action speed caused by manual firing. The structure and operating principle of the electric firing mechanism are illustrated. A parametric model is established. The electromagnet force of the electric firing mechanism is simulated in COMSOL, and the disturbance to LOS and response time of the electric firing mechanism is tested. The result shows that the mechanism is capable of electrically firing, the azimuthal disturbance of electric firing to LOS is reduced to 1/5 of manual firing, and the response time is 35 ms, which is much faster than manual firing speed. The electric firing mechanism will be helpful to catch the firing time precisely.
