摘要船舶航行抵达港口后，为了装卸货物和上下乘客，一般都停靠在码头旁，并由系缆设备将其牢固地系牢在码头上。船舶在停泊时，常受到以下三个力的作用：作用在船体水下部分的水流力；作用在船体水上部分的风力；由于船体纵倾和横倾时产生的惯性力。为了使船舶能够安全可靠地停泊，保持停泊时的位置不变，就必须要有一套设备来平衡这些力。

起锚机是船上重要的机械设备，对船舶安全锚泊和靠离码头乃至船舶避碰均有十分重要的作用。起锚机主要由基座、支架、锚链轮、刹车、链轮等组成。

本文的主要任务是液压起锚机的机械部分的设计。首先介绍了起锚机的工作特点，通过比较电动起锚机和液压组合式起锚机的结构，进行性能分析，了解到液压组合式起锚机的优越性，然后进行总体设计方案，再通过已给的参数要求对结构进行设计计算，核算选取各部件型号、尺寸、材料，最后运用Solidworks三维建模软件进行总体结构设计。49442

Abstract The ship sailed after the arrival in port, for loading and unloading of cargo and up and down passengers, usually docked at the quayside by the mooring device is securely fastened on the pier. Berthing of the ship, often subject to the following three forces: the role of water in the hull underwater part of the force; role in the hull water part of the wind; the inertia force in the hull trim and heeling. In order to make the ship berthed safely and securely maintain the berthing of the same location, you must have a device to balance these forces.

The windlass is important shipboard machinery and equipment, and rely on from the pier as well as ship collision avoidance have an important role in the safety of the ship at anchor. The windlass mainly consists of the base, bracket, anchor chain wheel, brake, sprockets and other components.

The dissertation primary mission is the Hydraulic combined windlass  part design. First introduce the characteristics of windlass, then compare the structure of the electric windlass and hydraulic windlass, then analysis their performance, so as to understand the superiority of hydraulic combined windlass.Through the parameter request which has gived  carried on the computation to the structure, Meanwhile carries on the overall structural design by using Solidworks model software.

KeyWords: Hydraulic combined windlass;  parked;  Structural design
