摘要
利用系统辨识方法对一艘液化石油气(Liquefied Petroleum Gas,LPG)船模型进行静水中横摇试验的辨识分析,建立船模静水横摇的数学模型。利用MATLAB软件中的动态仿真工具SIMULINK进行仿真验证,给出准确的横摇阻尼系数和附加质量惯性矩值,验证系统辨识方法在船模耐波性试验分析领域中的可靠性。该系统辨识方法可推广应用到船模及实船其他耐波性试验分析中。
The roll motion of an Liquefied Petroleum Gas（LPG）ship model in clam water is studied with the system identification technology.The mathematical model of the ship model is built from the experiment data.The roll motion of the ship model is simulated with the dynamic simulation tool SIMULINK,which shows that the simulation gives accurate roll damping coefficient and the added mass moment of inertia.This study proves that the system identification methods are reliable for analyzing ship model seakeeping performance in clam water.Extending the method to seakeeping performance tests under other water conditions is possible,either for ship model test or full scale ship trial.
