ABSTRACT
Xu, A. and Sun, J., 2015. The simulation study of marine propeller load characteristics based on regression algorithm.
In this paper, in order to avoid the complex calculation with propeller chart, a new model method for marine propeller was put forward. According to the new model method, propeller thrust and torque are calculated based on regression algorithm and it can realize four quadrants simulation. After the propeller model was completed, basic ship operation such as start, stop and emergency astern are simulated with the help of mathematical model of the ship-propeller. Through analyzing the change curves of the revolution speed of the propeller, the navigation speed of the ship and the torque of the ship under all kinds of working conditions, some operable suggestions and theory evidences are provided for the practical operation of the ship.
