摘要
采用数值仿真方法,建立半穿甲战斗部对航母甲板侵彻效应的数值仿真计算模型;确定了材料模型及参数;结合相关试验数据对模型进行验证。结果表明,在选取的6个正侵彻算例和3个斜侵彻算例中,弹丸穿过靶板后的剩余速度与相关参考文献中的相应实验测定值之间的最大相对误差和平均相对误差分别为6.81%和2.37%,且计算得到的破坏模式与实验结果相一致,验证了模型的有效性。该模型可应用于半穿甲战斗部侵彻航母甲板的毁伤效应研究。
FEM models of semi-armor-piercing warhead penetrating aircraft carrier deck are established by numerical simulation method,of which material models and parameters are determined and validated by related experimental data. The results show that maximal errors and average errors of calculated values of residual velocity relative to experimental results are respectively 6. 81% and 2. 37% for all the nine cases. And that deck damage effects obtained by numerical simulation are in accord with ones in related experiments. The FEM models could provide reference for penetration effect research of semi-armorpiercing warhead penetrating aircraft carrier target.
