锚体在锚穴底部固定轨道上运行的分析与研究

The Analysis and Research of Anchor Movement along a Fixed Orbit at the Bottom of Anchor Pocket:Anti-locked Anchor Pocket

锚穴的主要功能是把锚体储藏在船体的外板内部。其目的主要有防止锚体与其他物体(码头、船坞、等)碰撞,航行时能减少水浪对锚体本身的冲击,减轻风阻,减小对航速的负面影响等。最终能有效的把锚体沿设计的轨迹进入锚穴,并且顺利的与锚穴底板完全贴合,完成整个拉锚过程。由于一些锚穴在现代船舶建造中,受船体型线的制约,满足不了起锚任务。从而开展了从锚穴本身来改变锚体的运行轨迹的研究,利用锚穴底部的固定轨道将锚体顺利进入锚穴,最终完成起锚任务。

The main function of anchor pocket is to store the anchor inside the hull plate.There are many design purposes of the anchor pocket.It can prevent the anchor from colliding with other objects such as quay,dock and so on.The anchor pocket can reduce the colliding of waves and surge with the anchor while sailing,and the wind resistance so as to decrease the negative effect on ship speed.The anchor is able to be effectively put into the anchor pocket along the designed trajectory,and completely fit with the bottom of anchor pocket,then the whole process of drawing anchor is completed.In modern shipbuilding,some anchor pockets cannot satisfy drawing anchor test due to ship molded lines.In the study,anchor pocket itself was analyzed to change the running track of the anchor body.With the fixed orbit at the bottom of anchor pocket,the anchor finally entered anchor pocket smoothly,successfully fulfilling the drawing anchor test.
