Abstract
Influences of high stress caused by hull vibration on hull strength and fatigue life receives wide attention. Here, to study hull vibration response, the process of solving hull vibration response with hydroelasticity theory was introduced. The vibration response of an ultra large fast ship was simulated based on segmented model tests. Effect of wave height and speed of model on the vibration response was investigated, and the longitudinal distribution of vibration response was analyzed. Finally, the total moment and whipping response of this ship were predicted with 3D time domain nonlinear hydroelastic theory. The computational results obtained agreed well with the test data.
