摘　　要：为研究高速弹体侵彻液舱过程中的水锤效应和结构毁伤机理,本文开展了高速弹体侵彻液舱试验测试,得到了高速弹体入水产生的冲击波压力的传播和衰减规律,并采用高速相机记录了高速弹体侵彻液舱过程中空泡的演化过程。试验设计了不同厚度的液舱前后靶板,发现水锤效应使得液舱后板变形比前板更严重。此外,后靶板在侵彻过程中的变形会直接影响到反射冲击波压力的传播和衰减,较大的后靶板变形可显著缓解前靶板的变形情况。试验结果对舰船液舱结构的设计优化具有一定的参考价值。Experimental test of a liquid cabin penetrated by high-velocity projectile was designed to study the failure mechanism of hydrodynamic ram phenomenon during the penetration process.High-speed camera was used to capture the evolution process of the cavity with different thicknesses of front and back bulkhead of the liquid cabin.It is found that the out-of-plane deformation of the back bulkhead of the liquid cabin is always larger than that of the front bulkhead,which is mainly caused by hydrodynamic ram phenomenon.Moreover,the added distance between the front and back bulkhead caused by the deformation of the back bulkhead would make a difference in the propagation and attenuation of the reflected shock wave,resulting in a smaller deformation of the front bulkhead.The results of the experimental tests are helpful to the optimization design of liquid cabin structure of warships.
