高射速自动机气液式缓冲装置仿真分析

传统小口径武器一般采用弹簧式反后坐装置,其结构简单可靠但后坐力偏大。为进一步降低自动机后坐力,本文采用一种气体液压式反后坐缓冲装置,编制后坐运动数值仿真程序。仿真结果表明,在保证后坐位移的情况下,相比弹簧式缓冲器,采用气液式缓冲装置自动机最大后坐力下降了39%。对后坐运动过程进行流体仿真计算,并与数值计算结果进行对比,两者误差在10%以内,进一步验证了仿真结果。

Simulation of the Gas-liquid buffer device for High-speed automatic gun

The recoil systems of spring type are used in a wide range of existing small caliber weapons because of the advantages of simple structure.However,the recoil is larger than other types.To reduce the recoil further,a recoil system of gas-liquid type is studied in this paper.Numerical simulated program of recoil motion is designed.The simulation results indicate that the recoil reduced 39%used gas-liquid mechanism compared with the spring mechanism under the similar recoil displacement.The fluid simulation is conducted.The error values of numerical and fluid simulation are within 10%,which further validates the simulation results.
