骨架充气压力对自充式气囊缓冲性能影响研究
|
摘要
缓冲气囊作为一种着陆缓冲手段,具有质量轻,折叠性能好,成本低等优势,成为了回收着陆领域的重点研究方向。自充式缓冲气囊是一种利用环境气体作为缓冲介质的缓冲气囊,其主要依靠骨架式充气结构作为缓冲气囊展开的驱动。通过这种设计,可以有效减少缓冲气囊充气装置的携气量,拓展缓冲气囊的应用范围。文章对自充式缓冲气囊的工作原理进行了介绍,并对自充式缓冲气囊的缓冲过程进行了仿真研究。研究过程主要针对骨架式充气结构充气压力对气囊缓冲性能的影响进行了分析,并对其充气压力进行了优化选择。研究结果表明,对骨架式充气结构的充气压力进行优化,可以改善自充式缓冲气囊的性能。最后,引用相关试验结果,对优化结果后的充气展开性能进行了佐证。
As a means of landing buffer, airbags have light weight, good folding property and low cost,and are always the focus of soft landing research. Ambient inflated airbag mostly uses air of atmosphere to cushion vehicles aboard. It relies on inflatable frame to drive itself spread. This design can remarkable reduce the weight and volume of gas supply system, so as to expand the application scope of airbags. This paper introduces working principle of ambient inflated airbags, and researches the cushioning process of ambient inflated airbag by numerical simulation. Firstly, the landing and buffering simulation model is established.Then the influence of pressure in inflatable frame is studied. By researching cushioning process at different pressure in inflatable frame, a best value of pressure in inflatable frame is found. The result of this paper shows optimizing the pressure in inflatable frame can improve the cushioning effect of ambient inflated airbags.Finally, this paper verified the deployment behavior of the optimized results by quoting the results of relevant tests.
