摘要
为了充分发挥无人机集群作战的优势,能够在复杂环境和多样任务下快速、可靠地完成无人机集群发射任务,设计了一种折叠翼无人机集群发射装置。首先通过分析无人机发射过程主要性能指标,进行群发原理研究及装置总体布置。以发射技术指标作为输入,确定装置的动力匹配方案,基于几何学和运动学关系完成各机构的详细设计,利用偏心块组件和间歇机构的协调配合,将电机的动力分时分段传输给发射机构和输送机构,储能弹簧循环弹射无人机。最后利用LMS Virtual.Lab软件进行多体动力学建模仿真,仿真结果表明:电机功率、无人机发射速度和发射频率满足设计要求,设计方案具有可行性。
In order to give full play to the advantages of unmanned aerial vehicle cluster operation and complete the UAV cluster launch task quickly and reliably in complex environment and various tasks,a folding wing UAV cluster launch device is designed in this paper.Firstly,by analyzing the main performance indicators of UAV launch process,the principle of group launch and the overall arrangement of the device are studied.Taking the launch technical index as the input,the power matching scheme of the device is determined.Based on the geometry and kinematics relationship,the detailed design of each mechanism is completed.Using the coordination of eccentric block components and intermittent mechanism,the power of the motor is transmitted to the launch mechanism and transmission mechanism in time and section,and the energy storage spring is used to cycle eject the UAV.Finally,LMS Virtual.Lab software is used for multi-body dynamics modeling and simulation,the simulation results show that the motor power,UAV launch speed and launch frequency meet the design requirements,and the design scheme is feasible.
