摘要
为提高拖轮操纵模拟器的行为真实感,运用操纵性理论和分离型建模思想,建立全回转拖轮适用于四象限全工况操纵运动的数学模型。通过处理导管桨JD75系列和四象限螺旋桨Nordstrom系列试验图谱后,提出了导管桨四象限推力模型,同时提出了一种适用于全速域的拖轮船体水动力模型。搭建拖轮运动模拟平台,开展一系列操纵性仿真试验,包括速度试航试验、螺线试验、Z形试验、回转试验及停船试验。将仿真数据与Force Technology公司提供的试验数据进行比较分析,一致性良好,表明该模型精度可满足航海上仿真的需要。
In order to improve the behavioural realism of tug ship-handling simulator, a ship motion mathematical mod-el of azimuth tug is established by using the theory of maneuverability and separate modeling framework and this model is suitable for full-mission maneuvering range in four quadrants. By processing the ducted propeller JD75 character curves and four-quadrant propeller Nordstrom test curves, a ducted propeller thrust curve across four quadrants is put forward, then a hull hydrodynamic model for tug applicable to all speed range is proposed. The established simulation platform carries out a series of typical maneuverability tests, including speed trial test, spiral test, zigzag test, turning test and stopping test. In com-parison with simulation results and test data provided by Force Technology company, the model is reasonable and satisfact-ory, and its simulation precision can meet the need of navigation.
