适用于城市作战的柔性充气式侦察系统设计

The Design of Flexible Inflatable Unmanned Reconnaissance System for Urban Operations

城市战场建筑林立、明暗分明,且作战要避免对基础设施和平民造成伤害,对建筑内部的隐藏目标进行快速打击、定点摘除。需发展能克服室内空间及地下空间侦察通信难点、可深入建筑与废墟内部进行侦察的小型无人侦察系统。利用有线实现信息传输,设计仿植物生长尖端外翻柔性充气式侦察系统。首先阐述了柔性充气式侦察平台的设计方案及气囊转向装置的原理;然后建立气囊的有限元模型,利用控制体积法进行气囊充气生长过程中的动力学性能仿真,分析了所设计柔性充气式无人系统完成自生长、避障、穿越缝隙等设计目标的可行性,研究了各气室的充气速率对行进过程中速度、囊体表面所受压力的影响;最后做实物实验进行直行、转向测试,验证了该柔性充气侦察系统的实际工作性能。研究可为后续自生长气囊设计提供支撑,并为城市战场的侦察提供新思路。

Urban battlefield is full of architecture and easy to defend and difficult to attack.Flight need pay atten-tion to avoiding damaging infrastructure and civilians.It is necessary to develop a new small-scale unmanned recon-naissance system overcoming the difficulties of reconnaissance and communication in indoor space and underground space,realizing the reconnaissance in the interior space of the building.In this paper,a tip valgus soft pneumatic mobile platform is designed.Firstly the principle of air bag and steering device is described.Then the finite element model of the airbag is established.Simulation of the dynamic performance of the airbag during the growth process is realized by control volume method.The feasibility of the software design is studied.The influence of the inflation speed of each chamber on the velocity and the pressure of the bladder material is analyzed.At last,the real experiment is done for the straight and steering test.The actual performance of the flexible inflatable reconnaissance system is verified.This study can provide support for the subsequent design of self-growing airbag,and provide a new idea for the reconnaissance of urban battlefield.
