Time Domain Simulation of Vertical Ship Motions and Loads in Regular Head Seas

摘要

The time domain simulation of heave, pitch motions and wave bending moments is described in regular head seas. The small amplitude linear theory and a large amplitude nonlinear method based on the linear theory are used to predict ship motions and wave bending moments in the time domain. A series of measurements of ship motions and wave bending moments is carried out with a container ship model at different wave frequencies, wave amplitudes and forward speeds. The nonlinear theoretical prediction results are compared with the experimental data and there is a good agreement between them.
