云梯消防车梯架静力学分析

Structure design and statics analysis process of ladder for fire fighting ladder

云梯消防车梯架结构设计过程考虑因素比较多,只有将多方因素进行合理整合,才能够保证梯架结构设计顺利开展。梯架仿真分析结果是梯架结构优化的理论基础,必须严格规范有限元分析软件ANSYS Workbench对梯架结构进行仿真分析的过程,仿真分析过程包括:对梯架三维模型进行修复和补充,将其转化为有限元模型,将有限元模型根据最危险工况施加约束条件和载荷数据,进行结果分析和通用后处理,得出梯架结构在最危险工况时模型结构的位移图和组合应力图。根据计算结果对梯架结构进行优化,实现对梯架结构的精准控制。

There are many factors to be considered in the design process of the ladder structure.Only by integrating various factors reasonably can the design of the ladder structure be carried out smoothly.The results of simulation analysis of ladder structure are the theoretical basis of optimization of ladder structure,so the process of simulation analysis of ladder structure must be strictly standardized by finite element analysis software ANSYS Workbench.The process of simulation analysis includes first repairing and supplementing the three-dimensional model of ladder,then transforming it into finite element model,imposing constraints and loads on the finite element model according to the most dangerous conditions.Finally,the displacement diagram and combined stress diagram of the model structure under the most dangerous working conditions are obtained through the result analysis and general postprocessing.The structure of the ladder is optimized according to the calculation results,and the precise control of the structure of the ladder is realized.
