In order to improve the maneuvering safety of the ship in the course of turning,taking the change trend of the heel angle in the course of the cycle as the research object,a self-propelled model experiment platform was built to carry out the roll-turning experiment,and a high-precision DGPS device was equipped to obtain the data of the ship's turning motion track.Based on the trajectory points with the change of the heel angle in the experiment plotted by MATLAB software,
and the relationship curve between the GM and the heel angle fitted out, the law of the change of the heel angle was obtained,the regression formula was given and its reliability was verified,so that the ship maneuvering safety can be predicted according to the GM perturbation of the ship , which provides a reference for the ship maneuvering and maritime transportation.
Key words： ship; gravity metacenter(GM); heel angle; turning; self-propelled model
