| 摘 要： | 某架大型轰炸机的机翼Ⅰ大梁腹板被弹片损伤,使飞机不能执行任务。本文从机翼Ⅰ大梁腹板的受力情况出发,通过对损伤处的应力集中情况进行分析,采用止裂加强法对弹片损伤进行修理,使损伤处的最大集中应力由657.6MPa降低到339.4MPa,在腹板的许可强度范围以内,从而修理后的飞机完全满足任务执行的载荷要求。

| Abstract: | The venter board of I beam on a bomber was damaged by a shrapnel , it made the bomber not carry out missions . The paper analyzes the stress concentration of damage region according to the forces that the venter board of I beam bears , and presents a method of preventing damage from expanding and strengthening the board to repair the battle damage . The max concentrating stress is decreased from 657.6MPa to 339.4 MPa that is in the limit of permissive stress . The bomber can satisfy completely the load requirement of task . |
