Modelling and Simulation on Stopping Motion Based on Propeller C-Series in Maritime Simulator

Abstract

In order to improve the simulation accuracy of stopping motion of twin-propeller twin-rudder ship in maritime simulator, a new propeller map was used. The formulas were regressed by figures of Propeller C-series, which is proposed by Maritime Research Institute Netherlands(MARIN) for controllable pitch propellers(CPP). The thrust coefficient and torque coefficient of different pitch angle and pitch ratio were obtained by regression equation. The mathematical model of the ship motion was established based on separated modelling method. The resistance model was established and calculated by the Lap-Keller chart. The simulation tests were carried out both by MATLAB and simulator testing programs. The results were compared with real ship test data, which showed a great performance. The Propeller C-Series can significantly improve the simulation accuracy of the ship stopping motion in maritime simulator.
