Initiating a Mathematical Model for Prediction of 6-DOF Motion of Planing Crafts in Regular Waves

Abstract EN

Nowadays, most of the dynamic research on planing ships has been directed towards analyzing the ships motions in either 3-DOF (degrees of freedom) mode in the longitudinal vertical plane or in 3-DOF or 4-DOF mode in the lateral vertical plane.

For this reason, the current authors have started a research program of describing the dynamic behavior of planing ships in a 6-DOF mathematical model.

This program includes the developing of a 6-DOF computer simulation program in the time domain.

This type of simulation can be used for predicting the response of these planing vessels to the environmental disturbances during high-speed sailing.

In this paper, the development of the mathematical model will be presented.

Furthermore, a discussion will be offered about the use of these static contributions in a time domain simulation for modeling the behavior of planing crafts in regular waves.
