基于有限元的自动扶梯梯级安全性能研究
|
摘要
为保证自动扶梯梯级轻量化设计的同时具有较好的安全性能,运用ANSYS Workbench对自动扶梯梯级结构的刚度和强度进行了有限元分析。选取800mm型铝合金自动扶梯梯级,参照国家标准及规范要求分析其受载情况下的等效位移、von-Mises等效应力、固有频率及疲劳寿命等力学性能。研究表明:自动扶梯梯级的薄弱部分为主轮附近支撑结构。该分析方法和计算结果可为自动扶梯梯级结构设计提供一定参考。
In order to ensure the preferable safety performance of escalator rung during the lightweight design process,the finite element analysis of structure rigidity and strength characteristics of escalator rung was carried out by ANSYS Workbench.800 mm type escalator rung structure was selected.The equivalent displacement,von-Mises equivalent stress,natural frequency and fatigue life of escalator rung were analyzed according to requirements of national standards and regulations.The research shows that the weak part of the escalator rung is the supporting structure near the main wheel.The analysis method and results can provide references for design of escalator rung structure.
