摘要:
为探究吊耳根部焊缝开裂现象,采用有限元分析软件对吊耳焊缝的应力应变过程进行分析,得到焊缝截面上的应力分布规律,罐身直径1 400 mm的中药提取罐吊耳根部焊缝承受最大拉应力为148.98 MPa,其大于焊缝许用应力,焊缝易产生裂痕.通过加入补强筋板的方式,使其危险截面最大应力值降至77.08 MPa,有效地预防了焊缝开裂.
Abstract:
In order to explore the crack at the end of lifting lug, the finite element analysis software was used to analyze stress\|strain process of lifting lug welding and stress distribution on weld section was displayed. When diameter of can\|body is 1400 millimeter and maxximum tensile stress of weld at the end of lifting lug is 148.98 MPa,which is greater than the allowable tensile stress,the crack at the weld seam is formed easily.By using reinforcement plate, the maximum tensile stress on weld dangerous section decreased to 77.08 MPa to prevent weld cracking effectively.
