摘要：

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. © 2021, Editorial Board of Journal of Ship Mechanics. All right reserved.
