[摘要]地震频繁发生，对人身财产安全造成了严重威胁和损害。科研工作者和很多安全研究者都在设计研究能够在灾难发生时起到救援和自救的工具，包括生命探测仪、逃生工具、自救设备、挖掘机器等。其中针对灾难发生特点的工具比较少，这是因为人们对于灾难发生的侥幸心理和防范意识淡薄，绝大多数人都是灾害发生了才追悔莫及，所以提高灾难的预防意识，宣传灾难的应急措施，是很有必要的。最重要的是，能够把灾害影响止步于开始，研发制作自救工具。为此本文研究设计了针对洪水和地震灾害的自救工具。地震发生时间具有不确定性，发生在夜晚的概率比较大，造成的伤害更为严重，为了增加自救的成功率和及时性，将自救工具和床进行结合，优点是首先能够避免人睡觉时意识不清而造成的安全问题，其次能够有效的减少工具的空间占有量，还能起到一物多用的效果，既能放心使用，还能节约经济。市场存在一些抗震方面的床，其中有的做成仿古床,有的上面做成三角形，还有的做成发生地震时人掉到床体里，床板旋转成三角形，这种做法比前一种节省了很多空间，但是缺点是自动性不足，三角形容易产生应力集中，不安全的因素比较多。为了增加自救能力，提高救援效率，本文开发研究抗震自救床，其核心技术是纯机械传动。对于抗震自救床，首先进行市场资料调查,得到合适合理的数据,然后进行理论设计和建模,能够节省时间和经济,进行仿真实验,最后进行实际制作。设计自救床的抗震功能，包含材料选择，机械结构的设计等。进行了方案可行性的计算和利用有限元分析，包括应力、应变等。 [关键词]自救工具，抗震系统，系统可行性分析 DESIGN OF THE FLOOD PROTECTION AND ANTI-SEISMIC SELF-HELP BED [Abstract] I
