水线面大开口船舶阻力和耐波性试验研究

Resistance and Seakeeping Model Test of Ship with Notch

本文通过模型试验,对某水线面大开口船舶在开口开启和封闭状态下对船舶阻力和耐波性能的影响进行研究。试验结果表明:水线面大开口会产生较大的阻力增值,低航速下对船舶阻力的影响更为明显;同时,开口的存在会大幅度影响船舶在横摇方面的性能。

The resistance and seakeeping performance of a ship with notch in midship are studied in this paper.The model test is carried out to analyze the effects of open and closed notches on ship resistance and seakeeping performance.The test results show that the notch of waterplane will produce a large increase of resistance,the effect of the notch on the resistance is more obvious at low speed,and the existence of the notch will greatly affect the wave resistance of the ship in rolling.
