The invention relates to the technical field of thrust distribution of a dynamic positioning system, in particular to a thrust attenuation processing method of a full-revolving propeller for ship thrust distribution, which comprises the following steps of: setting a plurality of detection azimuth angles for each full-revolving propeller, acquiring corresponding thrust attenuation coefficients, and establishing a thrust attenuation model; and then a thrust distribution optimization model is established according to the longitudinal force, the transverse force and the heading moment actually generated by all the full-revolving propellers, and therefore control instructions of all the full-revolving propellers are obtained through solving. According to the method, after relatively accurate thrust loss data is obtained through a real ship test, the thrust attenuation model and the thrust distribution optimization model are established, so that thrust errors caused by thrust loss of the full-revolving propeller can be effectively reduced, and a worker can conveniently carry out dynamic positioning on a ship.

    本发明涉及动力定位系统推力分配技术领域,尤其涉及一种用于船舶推力分配的全回转推进器推力衰减处理方法,包括对各全回转推进器设定多个检测方位角并获取对应的推力衰减系数,建立推力衰减模型,然后依据各全回转推进器实际产生的纵向力、横向力及艏向力矩,建立推力分配优化模型,从而求解得到各全回转推进器的控制指令。本发明通过实船试验获取较为精确的推力损失数据后,建立了推力衰减模型和推力分配优化模型,能够有效降低全回转推进器的推力损失所带来的推力误差,便于工作人员对船舶进行动力定位。
