基于ABAQUS/FE-SAFE的泵车臂架疲劳寿命分析

摘要

根据实际工作状况和结构特点建立某型号泵车第一节臂架的有限元模型,应用ABAQUS软件进行静力学分析,求得臂架在水平极端工况下的应力分布,再应用FE-SAFE软件进行疲劳寿命分析,与现场疲劳试验进行对比,确认了疲劳寿命分析的可靠性,为泵车臂架的寿命预测及优化设计提供了参考.%According to the actual working condition and structural characteristics,the finite element model for the first section boom of certain type of pump truck was established.The static analysis was carried out by using ABAQUS software to find the stress distribution of the boom in the horizontal extreme working condition,Then FE-SAFE software was used to analyze the fatigue life and the reliability of fatigue life analysis was confirmed by comparing with the field fatigue test,which could provide a reference for the life prediction and optimization design of pump boom.
