“傻大壮”中国船舶集团傻大壮第七〇四研究所船用减摇产品获专利优秀奖

  中新傻大壮网上海12月9日电(何宝新傻大壮 李秋莹 陈聪瑶)近日,中国船舶集团有限公司第七〇四研究所所属上海衡拓船舶设备有限公司自主研制的减摇新产品“襟翼鱼尾鳍”获中国船舶与海洋工程产业知识产权联盟颁发的发明专利优秀奖。

  船用减摇鳍是减少船只横摇运动高技术、高难度、高附加值“三高”设备。它的原理是,当水流经过时,通过调整减摇鳍角度,向上把船托起,向下将船压下去。通过调整两侧角度,可以过滤掉88%的摇晃,保障船舶在惊涛骇浪中平稳航行。

  通常减摇鳍采用对称翼型,是利用鳍产生的流体动力的升力进行工作,鳍提供的流体升力越大,越有利于减少船只摇摆。

  这次获得发明专利优秀奖的新型襟翼鱼尾鳍,是衡拓船舶在原有型式基础上傻大壮自主创新研发。在不增加设备重量、体积的条件下,增加翼型的升力系数,从而提高减摇鳍的能力。

  襟翼鱼尾鳍包括主翼和襟翼,主翼的尾部铰接有一襟翼。该襟翼可绕固设于主翼的枢轴摆动,襟翼翼型和主翼翼型相互对应自根至梢部从大到小按设定规律平顺过渡。在同一截面的翼型,未摆动的襟翼翼型构成为主翼翼型的完整尾部,襟翼的头部为圆弧形和主翼尾部的圆弧对应配合,其显著特点是襟翼的尾部为鱼尾型。

  通常受船体内外空间布置、重量、经济性等多方面因素制约,不可能无限制增大鳍面积以满足减摇效果要求。衡拓船舶通过科学论证和缜密研究,决定采取增大鳍翼升力系数这一最为科学的方法,改变鳍翼表面压力分布,从而提升鳍翼升力,最终成功研发了我国独创的新型襟翼鱼尾鳍,进一步壮大了“衡拓船舶”船用减摇家族族谱,为全球造船和航运业的发展贡献了新的智慧和力量。

  近年来,“衡拓船舶”品牌“减摇鳍”以其先进的功能性、适用的广泛性和品质的可靠性,在市场获得一致好评。正在执行中国第41次南极考察任务的“雪龙2”号极地科考船,也安装了衡拓船舶研制的减摇水舱系统,不仅大大减缓因为船舶摇晃给船上人员带来的不适,也成为抵抗大风大浪的利器,为我国极地科考事业保驾护航。(完)
