摘要
设计一种滚装船机械式减摇装置,该装置利用运载的车辆和货物作为减摇质量体,在不减小船舶承载能力的前提下,可以有效提高系统的质量比,得到较好的减摇效果。详细阐述了各部分的结构和功能,并通过分析减摇装置的质量比、阻尼比和固有频率比对减摇指数的影响规律,得出各参数的最佳选择范围。以宝华号滚装船的参数为样本,确定了弹簧参数和阻尼器参数。仿真结果表明,减摇装置具有较好的减摇效果。
A mechanical type anti-rolling device for ro-ro ships was designed based on the principle of extended tuned mass damp- er. Compared with the existing anti-wiling devices, the device can he used not only for newly-buih ships, but also for the remodel of used ships since it has the advantages of lower modified cost and easy installation. The cargoes on board are used as tuned masses for the roll- ing control of the ro-ro ships in the design. The structures and functions of each part of the device are described in detail. The effects of structural parameters, such as mass ratio, damping ratio and frequency ratio, on the anti-rolling index are analyzed and an optimal range of each parameter is obtained. Taking the Baohua ro-ro ship as an example, the parameters of springs and dampers are determined.
