摘要
应用I-DEAS软件建立了自卸汽车U形架有限元模型,根据悬架系统的装配关系与U形架的受力特征确定了U形架的边界约束条件。应用有限元理论求解得到U形架分别在整车急加速、急减速、正常行驶单侧受力等极限工况时的应力大小及分布规律。分析结果表明,最大应力区域都在球铰连接板和拉板处,U形架无明显变形,验证了U形架结构设计合理,满足使用要求。
This paper applied I-DEAS software to establish the finite element model of dump truck＇s U-shaped frame.Based on the assembly relations of suspension system and the mechanics characteristics of U-shaped frame,the paper defined the boundary constraint condition of U-shaped frame boundary.By using finite element theory,the stress distribution of the frame was obtained respectively in the conditions of starting,braking and normal runing.The results show that the maximum stress and the maximum deformation of U-shaped frame are less the allowable values,the design of the U-shaped frame is reasonable.
