Impact Force Mechanism of a Trimaran Model and Its Experimental Validation

In recent years, trimarans have been used in high-speed transport and warships, but studies of them made little progress. We designed a trimaran model it to perform water-entry experiment find way reduce the slamming pressure. The process entering water was divided into several steps, different theoretical models were for each step, together with their force analysis. Relying on our experimental platform, we three flexible coating thicknesses six drop heights as working conditions. With an analysis results under these conditions, clearly indicates that cladding can decrease impact when slams water. Furthermore, corresponding analyses are validated by results.
