摘要
船用锚下落水阻力与锚在水平面的投影面积成正比,针对该投影面积不易获取的问题,统计分析AC-14型船用大抓力锚,Spek型、JIS型和Hall型普通无杆锚的尺寸,计算锚的水平投影面积,给出该投影面积与锚重相关的估算公式。
The horizontal projection area of ship anchor is an important role to the water resistance when it drops in water,which is hard to obtain. To solve the problem,dimensions of four types of ship anchors,including AC-14 anchor,Spek anchor,JIS anchor and Hall anchor were statistically analyzed,and the horizontal projection areas of those anchors were calculated.Based on data fitting,formulae were got for estimation of the projection area related to anchor weight,for the convenience of research.
