单兵肩射武器发射筒前盖破片后飞分析与改进
|
摘要
分析了前盖受弹丸头部撞击后破片飞散机理,根据前盖、制动环组件材料力学性能和结构设计,提出增加扩展防护圈、优化制动环组件结构方式以阻止破片后飞,采用ANSYS/LS-DYNA仿真软件计算其前盖的破碎过程,结合射击试验结果分析防护圈拓展后的安全可靠性,改进后的防护圈能可靠防止前盖碎片后飞。
Aiming at the phenomenon of fragments flying behind of the launch tube front cover,the mechanism of fragments flying away after the front cover was impacted by that the fuze head was analyzed.According to the material mechanical properties and structural desugn of the front cover and brake assembly,a method of extending the protective ring was proposed to prevent fragments flying back. The LS-DYNA software was used to calculate the crushing process of the front cover,also the safety and reliability of the expanded protective ring were analyzed in combination with the shooting test results. The improved protective ring can reliably prevent the front cover fragments from flying back,and the performance indexes of the weapon system are not affected.
