The influence of solid rubber coating on the transient response of floating structure to underwater shock wave is experimentally and numerically studied. A stiffened metal box coated with solid rubber tiles on the outer face is live-fire tested first. Based on the test results, a detailed numerical model is built by abaqus/explicit. Using the validated model, the influence of coating properties including density, nonlinear elasticity, compressibility and viscosity, on the wall pressure, global shock environment, and local bottom plate deformation of structure is investigated in detail. It is shown that solid rubber coating can change the incident pressure on the wet surface as well as the dynamic characteristics of the coated structure. The coating with high stiffness and low compressibility often enhances the high-frequency response on structure. The coating with high density and viscosity is helpful to reduce both the local deformation and global response.
