【摘要】 大型集装箱船航速高,主机功率大,实船航运中半平衡舵上易产生由空泡引起的剥蚀危害。为改善这种状况,在船研所空泡水筒进行了4 250 TEU集装箱船舵空泡试验研究。观察操舵过程中舵空泡产生的情况,探讨降低舵剥蚀的方法,延长舵的有效使用年限。更多还原

【Abstract】 Cavitation erosion happens easily on semi-balanced rudder of large container ship due to ship’s high power and speed.To reduce the danger of cavitation erosion on container ship rudder surface,an experimental study of rudder cavitation for a(4 250 TEU) container ship was carried out in the cavitation tunnel of SSSRI.The cavitation occurred on rudder surface in the case of different rudder angles was observed.Also the cause for rudder cavitation are analyzed and some measures for reducing rudder erosion are recommended for extending rudder life.更多还原
