The invention discloses a flat anti-rolling appendage device suitable for a triple-hulled vessel. The triple-hulled vessel comprises a main body and side bodies on the two sides, and is characterizedin that the structure of the flat anti-rolling appendage device is a flat plate with a wing-shaped section, the flat plate connects the main body and the side bodies into a whole under the water line,and the attack angle between the flat plate and the horizontal plane is not smaller than 0 degree. According to the device, the additional water mass and the rolling damping moment of the triple-hulled vessel can be increased through a large underwater contact area, so that the rolling amplitude is reduced, and the rolling motion of the triple-hulled vessel in waves is improved. The anti-rollingeffect of the device with the characteristics is 50% or above, and the sea-keeping performance of the triple-hulled vessel can be improved. The applicability of a real ship is highlighted, and the device can be used for selecting the stabilization appendage during the design of a triple-hulled ship, can be applied to various ships adopting the triple-hulled ship type, and is particularly suitablefor maritime search and rescue platforms, maritime scientific investigation ships, maritime law enforcement ships, high-speed transport ships and the like with excellent comprehensive performance.
本发明公开了种适用于三体船型的平板减摇附体装置,所述三体船包括主体和两侧的侧体,其特征在于,所述平板减摇附体装置结构为翼型剖面的平板,平板于水线下将主体和侧体连成一体,平板与水平面的攻角不小于0度。该装置通过较大的水中接触面积,可以增加三体船的附加水质量和横摇阻尼力矩,从而减少横摇幅值,改善三体船型在波浪中的横摇运动。具有上述特征的本发明装置的减横摇效果在50%以上,有利于提升三体船型的耐波性。本发明突出实船应用性,可用于三体船设计时减摇附体的选择,应用方向包括采用三体船型的各类船舶,特别适用于综合性能优越的海上搜救平台、海上科考船、海上执法船、高速运输船等。
