Simulation and Design Optimization for a Hydraulic Spring Floating Device

采用浮动机能够有效控制自动炮的后坐力及射击稳定性,对自动炮的适装性及武器系统的射击精度有重要作用。分析了液压弹簧式浮动机的基本结构和工作原理,建立了使用该原理浮动机的自动炮后坐运动数学模型,对使用本原理浮动机的某自动炮进行了十连发射击后坐运动的数值模拟,并对该浮动机进行了优化设计和仿真对比。优化结果缩短了自动机连发射击的最大后坐距离,能够提高该自动炮的工作可靠性;降低了最大后坐力,能够对炮架进行进一步的轻量化设计,提高自动炮装载平台的机动性。

The floating device plays an important role for automatic guns and the whole weapon system.It can effectively control the recoil and firing of the automatic gun.By analyzing the basic structure and working principle of the hydraulic spring floating device,we establish the recoil movement mathematical model of the automatic gun.A numerical simulation of ten bursts recoil movement of the automatic gun is presented to optimize the design.The results will provide a reference to shorten the maximum burst recoil length of the automatic gun,improve the operational reliability of the automatic cannon,reduce the maximum recoil,and improve the mobility of the automatic cannon loading platform.
