【摘要】 在现代动力定位系统中,主推进器经常和舵配合使用,组合单元的推力特性非常复杂,增加了动力定位控制分配的难度。文章首先从理论上推导了桨舵组合单元推力的数学模型,建立了组合单元推力与主推进器推力的对应关系。其次,进行了主推进器和舵联合作用下的水动力模型试验研究,通过对不同转速及不同舵角下组合单元的推力测量结果分析,对桨舵组合单元推力的理论模型进行了初步验证。最后,利用试验结果对桨舵组合推力模型进行了回归分析。本研究工作为解决舵参与动力定位控制时的优化推力分配问题提供了参考。更多还原

【Abstract】 The thrust characteristics of the propeller-rudder combination unit are very complex,which increase the difficulty of dynamic positioning control distribution.In order to simplify the treatment of the problem,thrust modeling of propeller-rudder combination unit is studied in this paper.Firstly,the theoretical thrust model is derived.The relationship between the combination unit and main thruster is preliminarily established.Then,the hydrodynamic force model test under the combined action of the main propeller and rudder is carried out.And the theoretical model is verified by the test results under different rotation speeds of main propeller and different rudder angles.Finally,a regression analysis is conducted,and a simple practical model is proposed.The results provide a meaningful reference for solving the problem of optimal thrust allocation when rudder participates in dynamic positioning control.更多还原
