    • Provided is a bell mouth design method whereby a bell mouth shape suitable for a ship type can be designed easily without depending on specific craftsmen. The bell mouth design method of the present invention has an initial shape setting step (Step 1) for setting the initial shape of the bell mouth 4; a three-dimensional model creation step (Step 2) for creating the three-dimensional model of the bell mouth 4 and other parts on a computer; a preliminary shape modification step (Step 3) for modifying the outer peripheral shape of the three-dimensional model of the bell mouth 4 so as to be rotatable when the anchor 3 contacts the initial shape of the bell mouth 4; a mechanical analysis step (Step 4) for performing a mechanical analysis of the condition of the anchor 3 being housed using the three-dimensional model of the bell mouth 4 and other parts on a computer; a determination step (Step 5) for checking whether the results of the mechanical analysis satisfy predetermined conditions; and a shape modification step (Step 6) for modifying three-dimensional model of the bell mouth 4 on the computer on the basis of results of the mechanical analysis
    • 提供一种喇叭口设计方法,其中可以容易地设计适合于船型的喇叭形状,而不依赖于特定的工匠。 本发明的喇叭口设计方法具有用于设定喇叭口4的初始形状的初始形状设定步骤(步骤1)。 用于在计算机上创建喇叭口4和其他部件的三维模型的三维模型创建步骤(步骤2) 一个初步形状修改步骤(步骤3),用于改变喇叭口4的三维模型的外周形状,以便当锚3接触到喇叭口4的初始形状时可旋转; 机械分析步骤(步骤4),用于使用喇叭口4的三维模型和计算机上的其他部件对锚固体3的状态进行机械分析; 确定步骤(步骤5),用于检查机械分析的结果是否满足预定条件; 以及基于机械分析的结果来修改计算机上的喇叭口4的三维模型的形状修改步骤(步骤6)
