摘要:
为了探索导气式水下枪械气室压力工作规律和水阻力对自动机运动规律的影响 ,设计了实验装置 ,在装置中以活动件模拟枪机 ,气体调节装置通过改变导气孔尺寸来调节活动件的后坐能量 ,机匣上的排水孔减少了活动件的后坐阻力。由装在实验装置上的专用传感器 (如应变测压传感器、感应测速传感器 )和其它测量仪器构成动力学测量系统。通过大量的实验 ,分别测定了活动件速度、膛压、气室压力和弹丸初速。数据分析结果显示 ,水阻力显著降低了活动件后坐速度 ,气室压力随实验用弹装药量、药室初始容积和导气孔尺寸的改变而改变 ,这些结论对水下枪械的动力学分析具有参考价值
Abstract:
To probe into the gas chamber pressure. s w orking law of gas-operated underw ater guns and the influence of w ater resistance on the automatic mechanisms. characterist ics of mot ion, a set of experimental equipment w as designed. In the experimental equipment, a moving part simulated a f irearm bolt . A set of gas regulat ing device adjusted the recoiling energy of the mov ing part by changing the size of gas-operated hole. The drainage pores in the receiver reduced the recoiling resistance of the moving part. Some specia-l purpose sensors, e. g. st rain pressure-measuring sensors, induct ion speed-measuring sensors, w ere mounted in the experimental equipment. T hese sensors and other measuring inst ruments const ituted dynamic measuring systems. After a large number of experiments, the velocity of the mov ing part , the pressure of cart ridge chamber and gas chamber, and the initial velocity of bullets w ere measured respectively. T he results of data analysis show that w ater resistance dramatically reduces the recoiling velocity of the moving part, and the gas chamber pressure varies w ith the propellant mass of experimental cartridges, the init ial volume of cart ridge chamber and the size of the g as-operated hole. The conclusions prov ide reference for the dynamic analysis of underw ater guns.
