摘　　要：可展收层合壳具有可变形、轻质、成形工艺简单、力学性能均匀等特点,在智能可变形结构上有潜在的应用价值。为了研究可展收层合壳的弹道冲击特性,使用一级轻气炮对三种不同材料制备的可展收层合壳进行弹道冲击试验,获得了不同速度下的冲击试验结果,分析了不同材料下可展收层合壳破坏形式的差异,并计算了相应铺层下可展收层合壳的弹道冲击试验中的总吸收能大小。对可展收层合壳侵彻试验进行了仿真模拟,并与试验结果相对比,验证了该仿真模型的准确性。使用验证后的仿真模型,分析了侵彻过程中弹丸的速度和加速度变化以及层合壳的破坏过程,计算了不同铺层层合壳的弹道极限速度。The deployable laminated shell has the characteristics of deformable,lightweight,simple molding process,uniform mechanical properties,etc.,and has great application value in intelligent deformable structure.In order to study the ballistic impact characteristics of the deployable laminated shell,the ballistic impact test of the deployable laminated shell of three different layup materials was carried out using a one⁃stage light air gun,and the impact test results at different speeds were obtained,the differences in the failure form of the deployable laminated shell under different layups were analyzed,and the ballistic limit speed of the corresponding substation deployable laminated shell and the total absorption energy in the ballistic impact test were calculated.The ballistic experiment of the deployable laminated shell was simulated,and the accuracy of the simulation model was verified by compared with the test results.Using the verified simulation model,the effects of different bullet types on the ballistic limit of the deployable laminated shell and its total absorption energy were calculated and analyzed.
