高楼逃生装置的减速原理分析

Principle analysis of deceleration of the high-rise escape apparatus

高楼逃生装置的设计原则是利用最短的时间,使更多的人安全地离开事发现场。此类设计所要解决的关键性难题是如何将逃生者的势能与动能平稳快速地降下来。采用负反馈闭环系统原理实现纯机械化设计,利用逃生人员自重实现自减速功能。对该装置进行减速原理进行分析,以便理解其整体结构设计与工作机理。通过Solidworks Simulation软件对减速结构重要零件进行有限元分析,找出该减速装置最容易失效的部位,有利于产品的设计与生产。

High- rise escape apparatus is designed to help more personnel escape safely from the scene in shortest time. However, how to ensure the escaping individual decrease potential energy and kinetic energy steady and fast is the key to the design. This design uses the principle of negative feedback close- loop system to achieve pure mechanical design, uses the escape personel self weight to realize self- dece Leration. Analyze the deceleration principle to understand its structural design and working mechanism. Making finite element analysis to the important deceleration parts through solidworks Simulation software to detect the weakest part is beneficial to product design and production.
