摘　　要：垃圾转运车是用于城市生活垃圾中转站转换容器工作状态和运输容器的一种专用车辆,其中重要的工作状态由拉臂实现。该文建立了不同了拉臂焊缝结构模型,分析其在危险工况下的臂架受力情况,利用Ncode软件进行疲劳寿命分析,经计算得出双侧30°焊缝结构疲劳寿命比单边50°焊缝结构长,且符合架体的应力和变形要求。Garbage transfer truck is a special vehicle used in municipal solid waste transfer station to change the working state of the container and to transport the container The important working state is realized by the pull arm.In this paperna different structure model of the pull arm weld is established,and the force of the boom under dangerous conditions is analyzed.The fatigue life analysis is carried out by using Ncode software.After calculation,the fatigue life ofthe double-sided 30-degree weld structure is more than that of the unilateral The 50-degree weld structure is long and meets the stress and deformation requirements of the frame.

关 键 词：垃圾转运车 焊缝结构 疲劳寿命 结构优化
