摘要：

The forces of sail in complex environment were analyzed, and the force functions of sail under the best attack angle were obtained. Based on the coupling relationship between ship motion and ship main diesel engine revolution, the fitting function of main diesel engine output torque and throttle lever position of ship was deduced. 76 000 DWT large ocean-going bulk ship `Wenzhuhai' was taken as research object, a sail-assisted ship motion model with four degrees of freedom was constructed based on real ship parameters. Simulation result shows that after adding sail, ship speed increases and roll angle decreases, but ship yaws more. Ship journey in the same time, ship speed under the best attack angle, and roll amplitude increase with the increase of wind speed after adding sail. Roll angle is less than 15° within safe range. Analysis result is consistent with the motion laws of real ship, so the model is effective. © 2015, Chang'an University. All right reserved.
