摘　　要：为解决自动扶梯的坠落问题,通过分析人因工程和材料力学,设计一种防坠落装置,建立装置的三维设计模型。通过对防坠落装置及桁架的力学有限元分析,得出桁架的有限元分析应力和挠度位移形变结果,按照桁架的安全设计规范及其材料特性进行比较和验证,确定方案的安全性和有效性,进而验证自动扶梯防坠落装置的实用可靠性。In order to solve escalator falling, an anti-falling device is designed by analyzing human factor engineering and material mechanics, and a three-dimensional design model of the device was built. The mechanical finite element of the device and its truss is analyzed to obtain the finite element analysis stress and deflection displacement deformation results of the truss. The safety and effectiveness of the scheme are determined by comparing and verifying the safety design specification of the truss and its material characteristics, and the practical reliability of the escalator falling prevention device is verified.
