摘要
研究了3 g柱形钢破片对4 mm厚钢靶板的侵彻能力及其工程计算模型。通过弹道枪抛射破片撞击靶板试验,得到了3 g柱形破片对4 mm厚钢板的弹道极限v 50以及破片和钢板的失效特征;采用De Marre公式作为工程计算模型,分析了试验结果的模型适用性以及计算值与试验值的一致性。结果表明:3 g柱形破片对4 mm厚钢板的弹道极限v 50为563 m/s,验证了De Marre公式工程计算模型,模型计算值与试验值具有良好的一致性。
Engineering calculation model and penetration resistance of 4 mm thick steel target to 3 g cylindrical fragment were investigated.Ballistic limit and failure features were obtained by ballistic impact experiment.De Marre equation was used as engineering calculation model to analyze applicability and consistency of experiment results.Results indicate that ballistic limit of 4mm thick steel plate against 3 g cylindrical fragment is 563 m/s.Experiment results are applicable to De Marre equation engineering calculation model.Model calculation has a good consistency with experiment value.
