弹体侵彻带加强筋结构靶的实验研究

以舰船结构为目标,设计了带加强筋的结构靶,并用模拟装药弹体对单层或多层模拟结构靶进行了侵彻实验。根据实验结果,建立了弹体侵彻结构靶板的剩余速度公式。分析了加强筋对靶板破坏模式和弹道参数的影响,对靶板吸收能量的情况进行了分析。结果表明,对于塑性较差的靶板,加强筋的刚度作用是影响靶板能量吸收和破坏模式的主要因素。实验结果对加筋防护结构的设计具有一定的参考价值。

The experimental research for projectile penetrating the structural target with rebar

According to the structure of warships,the structural target with rebar is designed, and the multi-layered space structural target with rebar penetrated by charged projectile is investigated experimentally. Based on the experimental results, the residual velocity formula is built up and the modes of destruction of the target is discussed. For the plasticity-less metal material target, the rigidity of the rebar plays a very important role in both the structural energy absorption by target and the modes of destruction. This paper could be helpful in the design of the protecting structures.
