摘　　要：结合工程实践采用第二临界状态的强度理论对某小口径榴弹发射时的强度进行了计算,并应用有限元软件对三种不同的工况进行了仿真分析,结果表明弹体与引信的连接部位为薄弱环节,当连接螺纹为M32、M33时壳体以及螺纹符合强度要求,当直径为M34时,由于壳体过薄不能够达到强度要求。The safety of projectiles in the chamber is very important.In this paper,the strength checking method of the second critical state is used to calculate the strength of a small caliber grenade at the time of launch,and the finite element software is used to simulate and analyze three different working conditions,and the results show that the connection between the projectile and the fuze is a weak link,and when the connecting thread is M32,M33 shell and thread can meet the strength requirements,when the diameter of M34,because the shell is too thin can not meet the strength requirements.

关 键 词：小口径榴弹 发射安全性 薄弱环节 强度
