Abstract Shipbuilding industry is a comprehensive industry and technical equipment for shipping and marine development and the defense, is an indispensable part of the manufacturing industry in China。 In the past decade, China's shipbuilding industry has developed rapidly, however, compared with Europe,America, Japan and Korea, the gap is still quite large。 Especially, the lagging behind ship supporting has restricted the development of China's shipbuilding industry。 And the total value of out-put of auxiliary ships takes about half of ship supporting, the windlass is one of them and plays an important role in the safe navigation。

The paper is the design of a Φ46 Marine Electric Windlass。 In this paper, using the knowledge of mechanical design and structural mechanics to study the mechanical structure。 Then, drawing electrical schematic based on the principle of electrical control to achieve mechanical and electrical integration。 After that, establishing a three-dimensional model to test and verify the structural strength and optimize it by motion simulation and finite element analysis。 Finally, writing the manufacturing process and instruction manuals。Study are as follows:

1。It mainly introduces the overall plan including the design of mechanical structure and electric control system。 The mechanical system includes four parts: drive device, drum shaft device, brake device and clutch device, which will be built a simulation model by SolidWorks。 The electric control system is Electrical Control Circuit in the Three-speed Cablelifter Motor。

2。Focuses on the mechanical structure design and check。 In the process  of mechanical structure design, calculation and check of key parts are done together。 At the same time, optimize the size of parts。

3。Then build a simulation model and do finite element analysis by SolidWorks, do stress analysis and deformation analysis to compare the theoretical calculations to determine the final structure。

4。Finally, prepare manufacturing plan and installation instructions。Draw the process technique for key parts and the instruction manuals and working principle notice and maintenance methods。
