摘要

为研究冰桨干扰过程中桨抽吸作用对冰运动轨迹的影响,本文基于循环水槽搭建了冰运动轨迹测量平台,结合Photron高速摄像机分析软件(PFA),对不同螺旋桨转速工况下冰的运动轨迹进行试验和分析.经过对试验结果的系统分析发现:当螺旋桨转速较大、流速较小时抽吸作用较为明显,会明显改变模型冰运动轨迹,甚至发生碰撞.当模型冰体积较大、水流流速较快时螺旋桨抽吸作用影响较小,抽吸作用很难改变水流流速带来的影响,对模型冰运动轨迹影响较小.

Abstract

In order to study the influence of propeller pumping action on ice trajectory during the process of ice propeller interference, this paper built a motion trajectory measurement platform based on circulating water tank, combining high-speed camera and the Photron FASTCAM Analysis (PFA) method, and tested and analyzed the trajectory of ice at different propeller rotation speeds. After systematic analysis of the test results, it is found that when the propeller rotates at a high speed and the flow velocity is small, the pumping action effect is obvious, which apparently changes the model ice trajectory and even makes the ice and propeller collide. When the model ice volume is large and the water flow velocity is fast, the propeller pumping action effect is small, and it is difficult for the pumping action effect to change the ice trajectory because of the influence of the water flow velocity, which has little effect on the model ice motion trajectory.

Key words： ice-propeller interference; circulating water tank; motion trajectory; pumping action
