| 摘要: |
| 介绍了一种无人机气动弹射系统的组成、结构、工作原理和发射过程。通过对其物理模型进行简化,采用基于封闭矢量环法与力平衡方程的联立约束法分析推导了该无人机弹射系统的动力学求解数学模型。在Matlab/Simulink环境中创建了弹射系统发射过程的动态仿真模型,得到了无人机的加速度和速度随时间变化的曲线等参数。并将遗传算法与Simulink有机结合,方便实现了气动弹射系统的仿真与优化。结果表明:该无人机弹射系统改善了现有弹射系统弹射加速度有明显峰值、发射轨道利用率低、发射长度过长等不足,为无人机气动弹射系统的工程研制提供了重要的理论参考,优化后进一步缩短了发射长度,减小了最大过载和加速度波动,为无人机气动弹射的系统级建模、动态仿真与性能优化提供了一个工作平台。 |

| Abstract: |
| The constitution,structure,working principle and launching process of an UAV pneumatic launcher aredescribed. Dynamic mathematical model of the pneumatic launcher is analyzed and established by using the simulta-neous constraint method based on the closing-vector-circle method and the equations of force balance by simplifyingits physical model. In order to get the parameters such as the variations of velocity and acceleration with time,thedynamic simulation model of the launching process is established in the environment of Matlab/Simulink. By combi-ning Genetic Algorithm with Simulink,the simulation and optimization of the pneumatic launcher are realized. Theresults and their analysis show preliminarily that: the pneumatic catapult launcher suppresses the drawbacks of theexisting launch devices such as requiring substantial space,acceleration peak,and low efficiency of track; it offerssignificant theoretical reference for the manufacture of the UAV pneumatic launcher. After optimization,the launch-ing length is shortened,the maximum of acceleration decreased and the acceleration wave is reduced. A workingplatform is offered for the modeling,simulation and optimization of the UAV pneumatic launcher. |
