中文摘要：

由于冰块临近和阻塞效应,将在螺旋桨上产生极端水动力载荷,进而导致螺旋桨诱导的空泡、嗓声以及激振力等性能的恶化.冰桨干扰作用是一个极其复杂的过程,受到诸多因素的影响,为了探究非接触工况下的冰桨干扰水动力特性,在循环水槽中搭建冰桨干扰试验台,并设计一套专门用于切削型冰模型的生成和制作的方法.通过试验重复性分析及与其他学者结果的比较,验证建立的冰桨干扰试验台的可行性.以切削型冰模型为对象,研究了非接触工况下的螺旋桨水动力载荷随冰桨间距变化的规律,探讨了不同流速对冰模型诱导的空泡的影响.试验结果表明：所建立的冰桨干扰试验方法是可行的,能够较好地用于冰桨干扰水动力试验的分析中.

英文摘要：

; As a result of ice approaching and blocking effect, marine screw propellers may be exposed to extreme hydrodynamic loads, leading to the deterioration of performances induced by a propeller, such as cavitation, noise, and vibration. The propeller-ice interaction is a complicated process that is affected by many factors. To study the characteristics of hydrodynamic non-contact loads during propellerice interaction, a testing apparatus of propellerice interaction was set up in a circulating water channel, and a building and manufacturing method for ice blocks was developed. The feasibility of the testing apparatus was validated through experimental repeatability analysis and a comparison with the results of other scholars. The characteristics of hydrodynamic non-contact loads at varying proximities of the propeller to an ice block and ice-induced cavitation versus water flow velocity were studied. Experimental results show that the method is feasible and can be used in the analysis of the hydrodynamic performance of propellerice interaction.
