摘要
为消除钢板挂舵臂的制造困难点,提出一种新的挂舵臂外形,即折线型外形,侧板的外表面由平面、圆弧面和圆柱面连接而组成。相对于常规外形,该折线型外形的优势是:能在建造过程中减少工作量,从而降低生产成本;对挂舵臂的强度和船体阻力无不利影响。
A new polygonal outline is specially designed for rudder horn to facilitate manufacture. The outer surface of its side plate is composed of plane, arc and cylindrical surface. Compared with conventional outlines, the polygonal outline has the advantages of less manufacturing work and lower production cost. The proposed outline has no adverse effect on the rudder horn strength or hull resistance.
