摘要
为探究发射过程中液柱平衡体对单兵筒式武器射击稳定性的影响,对基于液柱平衡体的单兵筒式武器动力学特性进行研究。通过分析采用液体平衡发射技术的单兵筒式武器发射过程,建立其受力模型;利用Fluent流体仿真软件建立喷管气液两相流仿真模型,重点分析液体工质对喷管推力的影响特性;并分析了液柱平衡体影响下单兵筒式武器膛线导转侧力的变化规律。研究结果表明:液柱平衡体对单兵筒式武器射击稳定性影响较大,有必要进一步优化设计。
In order to explore the influence of liquid-column equilibrium on the firing stability of single-barrel weapons,the dynamic characteristics of the liquid-column equilibrium weapon are studied.By analyzing the launching process of a single-barrel weapon using the liquid equilibrium launch technology,the force model of the launching process of a single-barrel weapon is established.The simulation model of gas-liquid two-phase flow in the nozzle is established by using fluent fluid simulation software,and the influence characteristics of liquid working medium on the thrust of the nozzle are mainly analyzed;and the variation law of rifling lateral force of individual barrel weapon under the influence of liquid column balance body is analyzed.The results show that the liquid-column balance has great influence on the firing stability of the single-barrel weapon,and further optimization design is needed.
