中文摘要:
      拖网渔业是世界上重要海洋渔业之一,在我国海洋渔业中也占有特别重要的地位。故拖网渔船的研究设计一向为各国所重视,而拖网绞车是它的一种关键性设备,影响作业的机械化程度,并直接影响渔船的作业效果,为此对拖网绞车的研究,不容忽视。 拖网绞车拉力是标志其性能的重要参数之一,其起网时之拉力值受渔船尺度和海浪情况、所用网具规格、起网速度等许多因素的制约,颇为复杂。
英文摘要:
      The trawl winch is an important equipment for trawlers.Data for theortical ana-lysis for its pull load have not been published as yet.In this paper, various fact-ors affecting pull load of trawl winch are being analysed completely. Derived calcu-lation method of pull load for various steps of hauling the trawl net was based onstatic balance and D'Alembert's principle in calm water and rough-sed. Finally, re-sult of actual ship experiment had been re-calculated by this method. The result ofthis paper was confirmed and may be designed for practical use and for productionof trawl winch.
