基于AMESim的拖网渔船的船机桨网匹配动态特性

Dynamical Characteristics of Hull-engine-propeller-net Matching of Trawler Based on AMESim

对某40m拖网渔船的螺旋桨特性曲线进行拟合,并通过Chebyshev多项式对特性曲线进行离散化处理。基于AMESim(advanced modeling environment for performing simulation of engineering systems)建立渔船仿真模型,将仿真结果与实船数据进行对比,验证该仿真模型的正确性。结果表明:在正常航行和拖网工况下,渔船的航速、推力、转矩等参数响应情况良好,船机桨网匹配合理。

A 40m trawler’s propeller characteristics curve was fitted,and the curve was discretized by means of Chebyshev polynomial.Based on AM ESim(advanced modeling environment for performing simulation of engineering systems)the trawler’s simulation model was built,and the simulation results were compared with the real trawler’s data to prove the simulation model’s validity.The results indicate that,under both navigation and trawling conditions,trawler’s speed,thrust,torque and other parameters respond well,and the hull,the propeller,the engine and the net match reasonably.
