摘要
高层建筑在危急时刻的快速逃生问题一直是个人防护设备领域中的研究重点,设计一款结构简单易操作高楼逃生设备成为必然。基于此,以众人熟悉的雨伞为模型设计一款新型自充气缓冲可调向逃生伞。并通过仿真分析软件模拟逃生伞降落过程中的伞表面压力分布大小,计算逃生伞下降时的气动阻力与伞结构参数关系,确定伞面结构尺寸,为逃生伞的产品制作提供参考,提高逃生伞的设计可靠性。
The quick escape of tall building in the critical moment has been the focus of research in the field of personal protective equipment, it is inevitable to design a escape equipment of simple structure and easy operation. Based on this, A novel escape umbrella was designed modeled on the familiar umbrella. Simulated the pressure size distribution of umbrella surface during landing by ANSYS Fluent software, and calculated relationship between the air resistance and the umbrella structure parameter When the escape umbrella landing, and determined the umbrella surface structure size. These provided reference for escaping umbrella products production and improved the design reliability of escaping umbrella.
