摘要
以贮气罐作为动力源、滑轮组作为增速机构的无人机气动弹射系统为研究对象,介绍了系统弹射过程的工作原理,基于键合图法推导出了系统的数学模型,并利用MATLAB软件建立了系统的仿真模型.通过对系统的不同设计参数进行仿真研究,得到了这些参数对系统弹射性能的影响规律,合理匹配这些参数,既可以优化系统的弹射性能,也为系统的研发与改进提供了理论的指导.
This paper introduces the working principle of an Unmanned Aerial Vehicle （UAV） pneumatic launch system, which takes an air tank as power supply and a pulley block as growth mechanism. The mathe- matical model of the system is deduced by using the bond graph method. And the simulation model is estab- lished by using MATLAB. Through adjusting the design parameters of the system, the influence of these pa- rameters on the launch performance is obtained. The haunch performance can be optimized by reasonable matc- hing of these parameters, which provides the theoretical guidance for this system.
