摘　　要：以新型贮气瓶供气气动弹射器为研究对象,建立了系统的数学模型,借助MATLAB仿真软件编制了系统的仿真模型,通过仿真研究获得了该弹射器阻尼孔对弹射过程中关键工作参数及系统性能的影响的规律,为详细设计该系统提供了依据。By taking a new type of pneumatic catapult powered by gas tanks as the research object,the mathematical model of the system was established,and the simulation model of ejection system was programmed using MATLAB simulation software.The rules of influences on main working parameters and performance of system by the damping hole of the catapult have been obtained in the ejec-tion process through the simulation research.Thus it lays a theoretical foundation for the detailed design of the system.
