【摘要】 在单桨船自航性能预报二因次与三因次标准方法与规范的基础上,提出一种耙吸拖力自航试验及实船耙吸拖力预报方法。选取5条不同型号的双桨耙吸挖泥船进行模型试验,分别用二因次与三因次方法对耙吸拖力进行预报。根据预报结果对三因次法中的功率因子与转速因子进行回归分析,比较两种方法的最终预报结果,验证了所提方法的合理性、有效性。更多还原

【Abstract】 Based on the standard 2D and 3D methods in performance prediction for the single propeller ship,a method was proposed for self-propulsion test in dredging condition and full scale drag force prediction for the trailing suction hopper dredger.Model tests were conducted with five different twin propeller trailing suction hopper dredger models.Full scale ship drag force was predicted in 2D and 3D methods,and the effectiveness of the proposed method was validated.更多还原
