某火炮新型转膛自动机抛壳机构分析

Analysis of Shell Mechanism of New Type Rotary Gun

某火炮新型转膛自动机为提高射速,减少了基础构件的工作行程。然而基础构件工作行程的减少却导致了抛壳滑块行程不足,以致抛壳失败。为了使该自动机抛壳顺利完成,设计了加速机构,并分析了其在抛壳中的影响。通过ADAMS软件建立了抛壳加速机构的运动学方程,运用虚拟样机技术对该机构进行仿真分析。分析结果表明,该机构加大了抛壳滑块运动行程,能有效改善抛壳情况,使抛壳顺利完成。

In order to improve a new type revolving chamber gun＇ s firing rate, it needs reducing the working stroke of basic component. However the cartridge ejection slider＂ s stroke is reduced too, thus resulting in the failure of the certridge ejection. In order to successfully complete the cartridge ejection, this paper designs the acceleration mechanism and analyzes its influence on the cartddge ejection. It also uses the software of ADAMS to establishe the kinematic equations and uses the virtual prototyping technology to do the simulation analysis of the accelerating mechanism. The analysis results indicates that the mechanism is used to increase the working stroke of the cartridge ejection slider, improve the situation of the cartridge ejection, and complete the cartridge ejection effectively.
