摘要
弹体在跌落撞击钢板过程中,弹体上将会叠加非常复杂的震荡信号,这些震荡信号对实际过载信号的提取和分析将造成不可忽视的影响。本文通过将实弹跌落至钢板,采集到弹体在碰撞钢板过程中的过载信号和弹体上的各阶震荡信号,并对这些震荡信号进行频谱分析和AN SY S有限元模态分析,为弹体的碰撞过载数据分析提供了帮助。
When the shells fall off and impact to the armor plate, a complex shock signal is added to the shell. The shock signal causes an innegleetable influence on the real overload signal analysis. Experiments are performed to obtain the overload signal and the vibration signals when the shell impacts to the armor plate. These signal are analyzed by the spectrum analysis and ANASYS analysis. The result is helpful for the penetration test.
