摘要

将叉吊搬运车的回转支承设置于叉车门架横梁中部,实现横梁上的伸缩臂可左右摆动的承弯抗扭门架结构,运用Ansys Workbench对其进行有限元分析、结构优化研究。通过以不同板厚、不同结构尺寸为设计变量,以布置构造尺寸、强度、抗屈曲稳定性等为约束条件,对各不利工况进行结构分析与优化,再对所有工况进行验算,得到在轻量化目标下的各优化结果及其圆整值。以利于充分发挥箱型门架的承弯抗扭性能,有效地实现轻量化设计,可为类似结构的优化提供参考。

Abstract

This paper aims to study the forklift truck,which installs forklift in the middle section of a mast and creates the telescopic boom subjected to Bending and Torque Moment. FEA and Structure Optimization are carried out through ANSYS Workbench. Under the constraint conditions of size,strength,the stability against elastic buckling,and with board thickness and structure sizes as the design variables,disadvantageous working conditions are analyzed and optimized,all working conditions tested and verified,and optimal results and their rounds received under the goal of lightweight. This paper intends to find a way to fully realize the subjectivity to bending and torque moment,and lightweight design,and to work as reference for future lightweight design.
