摘要
采用250kg半穿甲砂弹内植入过载仪对C40混凝土、RPCI20、块石固结体等靶体进行了侵彻过载测试，获得了过载原始曲线。采用模态和频谱分析得到了弹体频响基频，进行了低通滤波分析。由Forrestal模型及贯穿过载模型分析得到了厚靶和薄靶过载的计算公式，对理论计算结果与测试结果进行了分析比较，得到了大口径弹体过载曲线的基本特征。
The original deceleration-time curve of penetration was acquired by overloading test on penetration into C40 concrete , RPC120, nubby stone concretion with a 250 kg semi-armor-piercing projectile with an overload instrument embedded in it. Through modal and frequency attained, and low-pass filter analysis was done. The formula overload model analysis. And the principal character of the by comparing theoretical calculation with test results. spectrum analysis, the characteristic frequency was was achieved based on Forrestal model and perforation overload curve of large-diameter projectiles was found
