Structural Response Analysis of a Cylinder under Water Impact

摘要: This paper describes a method for estimating the structural response of ship structures under water impact pressure. A series drop tests cylinder with diameter 312 mm was carried out to measure pressures and strains on surface cylinder. Numerical analyses were one reproduce measured time history pressures. In spite existence large local vibrations shown in numerically estimated strain values, values mainly showed same tendencies. result confirmed that numerical employed here can be used this purpose. The effects maximum pressure value evaluated. Two types histograms estimate values. obtained from histogram less effect than without Finally, analysis modified. One had twice as much other mean before after peak value. results itself has little value, while integration seems have more
