新型零航速矢量减摇系统研究

针对海洋科研平台、科考船等减摇系统的快速响应性工作需求,在螺旋桨推进器基础上开发了一种零航速矢量减摇系统。本文介绍系统机构设计及其工作原理,结合耐波性计算分析获取船舶横摇规律,采用滑台搭载重物往复移动方式,模拟船舶规则横摇以获得规则波实验条件,并通过船模实验验证该减摇装置作用下的船舶横摇减摇效果。零航速规则波模拟实验研究表明,该减摇装置具有可控性强、易改装的特点,能够大幅提高船舶的耐波性,为后续工程试验船舶上安装该减摇系统奠定理论与实验基础。

Research of a novel zero-speed vector anti-rolling system

In allusion to satisfy the work demands of marine scientific research platform and scientific research ship,and to improve the fast response characteristics of the anti-rolling system,a zero-speed vector anti-rolling system is developed based on the principle of propeller systerm.The mechanism design was introduced and the operational principle was analyzed.Based on seakeeping analysis was carried out,and the linear ship rolling was simulated by the reciprocating moving weight carried by the sliding table to simulate the regular wave experimental conditions.The anti-rolling effect of the system was verified by the simulation experiment.Simulated experimental research of zero-speed regular wave shows that the anti-rolling device has the characteristics of strong controllability and easy to modified,which can greatly improve the ship's seakeeping resistance and can establish the theoretical and experimental foundation for the installation of the antirolling system on the engineering test ship.
