齿轮增速式液压弹射器弹射过程的仿真分析

Simulation Analysis on Hydraulic Catapult Ejection Process of Gear Increaser

以齿轮增速式液压弹射器的弹射过程为研究对象,运用功率键合图法建立了弹射过程的数学模型,利用MATLAB软件建立仿真模型并进行了详细的仿真分析,得到了弹射过程中关键参数对弹射性能的影响,为中重型无人机弹射起飞的研究提供了理论依据。

The hydraulic catapult ejection process of gear increaser is considered as the research object. We use the power bond graph methods to establish the mathematical model, build the simulation model by MATLAB and use it to carry on the simulation analysis. Finally, the influence of key parameters on the ejection performance is ob- tained, which provides a theoretical basis for the research of the launch of the medium and heavy UAV.
