摘要
以某小口径机枪为例,结合GJB3484—98枪械性能试验方法,利用ANSYS/LS-DYNA软件对其侵彻钢靶松木靶进行了仿真分析,其结果与试验结果相吻合。表明:仰射状态射角大于23°与俯射状态射角小于-15°时,弹头均不能穿透靶标,实现了该机枪威力的综合考核。
By the combined method of trajectory calculation and fem simulation,taking a small diameter machine gun as an example,according to GJB3484-98 gun performance test method,the simulation analysis of penetrating steel and pine target was carried by ANSYS/LS-DYNA software and the simulation model was consistent with experimental results.The results show that the overhead shooting angle is greater than 23°and prone shooting angle is less than-15°,and cannot penetrate the target,which implements the comprehensive assessment of the machine gun power,enriches the contents of power assessment,and provides technical means to the power prediction for all kinds of firearms.
