为减小枪机质量和速度,采用在弹膛内开槽的方法。利用ABAQUS软件对弹膛未开槽和开槽两种状态下枪机后坐过程进行仿真,得到枪机的速度、抽壳阻力等变化规律。仿真结果表明,膛内开槽可以有效降低枪机后坐速度。
為減小鎗機質量和速度,採用在彈膛內開槽的方法。利用ABAQUS軟件對彈膛未開槽和開槽兩種狀態下鎗機後坐過程進行倣真,得到鎗機的速度、抽殼阻力等變化規律。倣真結果錶明,膛內開槽可以有效降低鎗機後坐速度。

The grooves were made on the chamber to reduce the velocity and the mass of the bolt .The recoiling process of bolt was simulated by the ABAQUS software in two conditions of chamber with grooves or not ,and the velocity of bolt ,the extracting force were obtained .The result reveals that chamber with grooves can decrease the velocity of bolt effectively .
