高空作业车车臂轻量化设计及参数优化
摘要
Abstract
Considering that the unreasonable cross-section design of the boom of aerial working platform leads to the excessive weight of the whole vehicle,which leads to the failure of normal operation in the city,a lightweight design of the boom of an aerial working platform with an operating height of 23 m was carried out.The strength and stiffness conditions of the working boom were analyzed,and a finite element model of the lifting of the vehicle boom was established,and the reliability of the finite element model was verified by the real vehicle test.Based on this model,taking the cross-section height,width and thickness of the four-section boom as variables,and the weight and deformation of the working boom as the objective,the multi-objective optimization was carried out by NSGA-Ⅱ genetic algorithm.The results show that when the angle of the working boom reaches 50 degrees,the working boom is in the most dangerous working condition,and the dangerous point is the hinge position between the basic boom and the hydraulic cylinder.After optimization,the weight of the boom of this aerial working platform is reduced by 105 kg and 18.5%,which provides a design method for the lightweight of the boom of aerial working platform.关键词
