用弹道摆可直接测量弹道穿透阻力,而避免常规的统计分析,提高了测试精度。符号 M:初始弹丸质量 M_r:剩余弹丸质量 m:散脫金属板总质量 V:碰撞速度 V_(rP):弹丸剩余速度 V_(r):散脫金属板材的剩余速度 I:转換到金属板支座上的冲量 W:所做的功
With the ballistic pendulum can directly measure the ballistic resistance, and avoid the conventional statistical analysis, improve the test accuracy. Symbol M: initial projectile mass M_r: mass of remaining projectile m: total mass of loose metal plate V: collision velocity V rp: residual projectile velocity V r: residual velocity of loose metal plate I: transition to metal plate Impulse on the support W: work done
