摘　　要：某转膛自动机在研制过程中,多次出现连接筒U形槽根部断裂现象。根据转膛自动机工作原理,分析了连接筒与主动滑板、推弹滑座等零部件之间的连接关系以及运动特性。在一定简化与假设的基础上,建立撞击模型,应用撞击变形能理论,对连接筒撞击时受力进行了分析与计算。通过采取加大U形槽根部圆角半径和在炮箱上增加限位块等措施,减小了推弹滑座与连接筒在后坐到位时的撞击力和应力水平,提高了连接筒的使用寿命。Aimed at the joining cylinder fracture problems of revolver type automatic gun,the joining relation of automatic gun and fracture of the cylinder were analyzed,the reason of cylinder facture is given.Based on proposing certain simplification and assumption,the cylinder＇s model was built and its stress was calculated by material mechanics to find out the factor effects of stress in cross section in the case of multiple continuity impacts.After mounting a spacer in receiver and proving test,the cylinder meets the requirements.
