摘　　要：采用Ansys有限元分析软件针对发夹式循环冷却器的法兰U型扁弯壳结构进行静力学分析和强度校核。基于有限元模拟结果,依据标准JB 4732—1995进行强度校核的结果表明,在U型扁弯壳封头极值路径处,一次应力与二次应力之和为397 MPa,超出许用应力值351 MPa,强度校核不合格。设置3个轴向加强筋板和1个竖直方向加强筋板后,U型扁弯壳封头的最大应力由515 MPa下降至124 MPa。The static analysis and strength check of the flange U-shaped flat curved shell structure of the hairpin circulating cooler were carried out by Ansys finite element analysis software.Based on the finite element simulation results and according to the standard JB 4732—1995,the strength check results show that at the extreme path of U-shaped flat curved shell head,the sum of primary stress and secondary stress is 397 MPa,which exceeds the allowable stress value of 351 MPa,and the strength check is unqualified.The maximum stress of U-shaped flat curved shell head decreases from 515 MPa to 124 MPa when three axial stiffeners and one vertical stiffener are installed.
