摘　　要：机翼壁板裂纹是飞机服役中普遍遇到的损伤,贴补加强是典型的修理方案。本文通过试验和计算机仿真分析,研究修理部位的受力情况,给出了修理后的危险部位,并对模拟结果与试验结果进行了对比,结果吻合较好。同时,得到了机翼壁板试验件的典型开裂模式,对工程断裂问题研究有较好的参考价值。Wing panel crack is universal phenomena in the daily use of aircraft,which is typically repaired by strengthening the board.The stress distribution in the repaired position is studied by experiment and computer simulation.Dangerous areas after repair are given.It is found that the simulated results agreed well with the experimental results,and the typical crack growth mode is obtained,which provides a reference for engineering fracture problems.
