家用救生舱的概念设计

Conceptual design of family refuge chamber

针对在地震、火灾等突发的自然灾难中房屋建筑遭到严重的损害后住宅内的被困人员生命无法得到保障的问题,设计出了一种可以保障被困人员生命安全的新型家用救生舱;对该救生舱的总体设计方案进行了简要介绍,给出了救生舱的结构简图;利用有限元分析软件对救生舱舱体进行了静载分析,根据得到的舱体表面应力云图和位移形变云图对舱体抗冲击性进行了强化;提出了提高该救生舱耐温隔热能力的舱壁结构设计;设计了可以满足被困人员生存需求的救生舱内部生存保障设备。研究结果表明,该家用救生舱不仅抗冲击、耐高温、密闭性好,且其完善的保障设施能为被困人员提供一个稳定可靠的维生空间。

During earthquakes, fires and other emergent natural disasters, the buildings will be destroyed severely and the trapped lives can not be guaranteed. Aiming at this problem, a new family refuge chamber was planned. The overall design of the family refuge chamber was introduced briefly and the structure diagram of the chamber was shown. Besides, the strength of the chamber was analyzed by finite element software and the impact resistance of the chamber was strengthened based on the equivalent stress nephogram and the displacement deforma- tion nephogram of the chamber. What＇s more, the structure of cabin was designed which can improve the high temperature resistance of the chamber. And the life-support system necessary for the survival of the trapped was also provided inside. The results indicate that the family refuge chamber not only has impact resistance, high temperature resistance and good tightness, but also is configured a perfect life-support system inside, which can provide a reliable and stable living space for the trapped.
