急 “直筒段容积”用英文怎么表达? 铆接工具夹紧套筒的有限元分析及辅助设计 吴建忠1 程晓鸣1 孙全龙2 1 上海交通大学 2 上海安字铆接工具厂 摘 要:采用ansys有限元分析软件 ,对夹紧套筒进行了应力计算 ,以确定夹紧套筒的结构形式。在相同的载 荷作用下 ,在承载的锥面外端增加直筒段结构可以有效地减低最大变形量和最大应力值 ,使应力分布均衡。表明 直筒段结构提高了夹紧套筒的刚度和承载能力 ,有效地提高了夹紧套筒的使用寿命。 关键词:铆接工具 , 夹紧套筒 , 有限元分析 , 辅助设计 finite element analysis and aided design of closing sleeve in riveting tool wu jianzhong cheng xiaoming sun quanlong abstract : the stress of clamping of the closing sleeve is calculated by means of finite element of ansys to optimize clamping structure. adding a section of cylinder out of loaded cone can reduce availably the transformation and stress , equalize stress and improve stress concentration zone. the study reveals that the section of cylinder can heighten the rigidity and loading capacity and prolong service life of clamping. keywords : riveting tool , closing sleeve , finite element analysis , aided design查看更多
