A ship separation anti-rolling device based on steel ball sliding rail and electromagnetic connection relates to the anti-rolling technology of offshore vessels or yachts. The hull is provided with a hull and a hull gallbladder, and the hull and the hull gallbladder are connected by a steel ball, and the hull and the hull gallbladder are connected with each other through an electromagnetic connector at the stern part of the ship. The two sides of the hull shell can be designed in a smooth streamlined shape without adding any parts that hinder the high-speed navigation of the hull. The hull can be provided with a hull sliding rail, the hull can be provided with a hull gall sliding rail, and at least one steel ball can be arranged between the hull sliding rail and the hull gall sliding rail, which can only produce relative sliding in the transverse direction, and can not produce separation or other forms of motion. It has the advantage of reducing roll zero delay and is not restricted by speed. Therefore, it can achieve the goal of stable hull and reducing roll to the maximum in the range of full speed of hull and in the condition of small and medium-sized wind and wave in the offshore area.

一种基于钢球滑轨和电磁连接的船舶分离式减横摇装置
本专利技术涉及近海船只或游艇的减摇技术,尤其是涉及减少船舶横摇的一种基于钢球滑轨和电磁连接的船舶分离式减横摇装置。
技术介绍
船舶在海浪中航行,由于受到风、浪、海流等因素的影响,将产生六个自由度的运动:横摇、纵摇、艏摇、横荡、纵荡、垂荡。对这些运动的控制不当,会引起姿态失稳,危及船舶航行安全([1]PerezT,BlankeM.Shiprolldampingcontrol[J].AnnualReviewsinControl,2012,36(1):129-147)。船舶在河海中航行时的摇晃以横摇为主,为了减少船舶的横摇,一般船体上都会被改造装上一些减横摇装置。在一些游艇为主的奢侈品中,舒适性成为衡量游艇优劣的非常重要的指标。减摇鳍是目前效果比较好、应用范围广、装船量高的一种减摇方式。但是,减摇鳍只是在高速下减摇效果明显,在低速以及零航速下减摇效果很不明显。减摇水仓应用范围也比较广,减摇水仓利用船内反向力矩的作用,减摇效果也非常好,但是减摇水仓对船体的改动较大一般占到全船约1%~4%的排水量,不适合中小型机动性能高的船只。利用重物在转动系统中沿径向方向运动时的科氏效应,日本横滨国立大学的Hirakawa等([2]HirakawaY,HirayamaT,KakizoeK,etal.SeatrialofprototypeVerticalWeightStabilizer(VWS)anti-rollingsystemforsmallships[J].JournalofMarineScience&Technolo ...
