چکیده انگلیسی
A hydro-elastic 2.5Â m wave piercing catamaran model with a short centre bow has been tested in random head seas. Slamming wave impacts were found to be close to the aft end of the short centre bow. These occurred at time intervals of over 3 encountered modal wave periods, with longer intervals in smaller seas and for shorter modal periods. Slams were only detected in wave heights exceeding 1.5Â m at full scale. Slam loads in 4Â m seas were mostly about 25% of the hull weight but some reached 132% of the hull weight. Slam durations were generally about 0.35Â s at full scale. Slam induced bending was found to reach 11% of the product of hull weight and length. Simulation of slamming within a time domain seakeeping computation showed slightly higher median relative velocities at the slam instant than was observed in the model tests.
