Abstract

In this paper, a high speed mono-hull ship is taken as the research object, and the roll decay tests are carried out under different drafts and different initial rolling angles of two ship models with or without bulbous bow, The movement process of the roll motion of a high speed mono-hull ship is studied by rolling test. A mathematical model of system identification for roll motion of high speed mono-hull ship based on genetic algorithm (GA) is established, and a calculation program is compiled and a practical example of the roll of experimental data is calculated. Compared the experimental results and the identification results, two reasonable mathematical models of roll motion are obtained, which provides a basis for further study on high speed mono-hull ship performance, meanwhile verifies the system's reliability.
