摘要：在船用螺旋桨制造领域中，复合材料凭借其质量轻，比强度、比刚度好，耐腐蚀，耐疲劳等优势逐渐得到应用。其中，碳纤维是一种最为典型的高性能增强复合材料。在发达国家，碳纤维螺旋桨铺放工艺已发展得较为成熟，相比之下，我国在这方面的研究尚且出于初级阶段。采用碳纤维的船用螺旋桨较常规合金材料而言，除了力学性能、抗腐蚀性能大大提升之外，表面质量也大有提高，运动船体噪声将大大减小，这对于我国国防事业有着重大意义。

针对具有大曲率表面的船用可调式螺旋桨，本文设计了六自由度并联式的碳纤维螺旋桨铺放设备。结构上主要包括运动功能、铺放功能、螺旋桨装夹功能以及用于工件支撑的辅助功能四大部分。运动功能模块和铺放功能模块是设计的重点，运动功能模块是基于Matlab对六轴并联结构尺寸进行设计计算，再利用Solidworks进行运动仿真，铺放功能模块则根据丝束的传递路径上分别对实现导向、张紧、切割、重送、加热、压实、冷却等功能的结构进行设计。

控制部分主要包括运动控制系统和铺放功能控制系统两大部分。运动控制采用固高GTS800运动控制器，通过VC++编程，开发出可执行G代码加工指令的人机交互软件。铺放功能控制采用可编程逻辑控制器，执行铺放过程中各功能的开关通断。

Abstract：In the field of the marine propeller manufacturing,composite materials, with its light quality, high specific strength, high specific stiffness, great corrosion resistance, great fatigue resistance and other advantages,has been applied gradually.Among them,the carbon fiber is one of the most typical high performance reinforced composites.In developed countries, carbon-fiber propeller placement technology has developed maturely.By contrast, in China,it is still in the primary stage in this aspect of the research.Compared with marine propellers using conventional alloys,marine propellers with carbon fibre greatly improve the surface quality,besides to enhance the mechanical properties and corrosion resistance,therefore greatly reduce the noise while running.So it has a great significance for China's national defense.

For large curvature on the surface of the marine propeller,this paper designed the carbon-fiber propeller placement machine with six-degree of freedom parallel.The structure mainly includes four parts,which are movement function module,placement function module,the propeller clamping function module and support function module.Movement function module and placement function module are the key of the design,the movement function module is based on Matlab of six axis parallel structure size design and calculation,using Solidworks motion simulate.Placement function module is respectively designed according to the pass of tow path which achieves orientation,compression,cutting,heavy to send,heating,compaction,cooling.

Control part mainly includes the motion control system and placement function control system.Motion control system with Googol GTS800 motion controller,through VC++ programming,has been developed executable G code processing instruction interactive software.Placement function control system is developed by programmable logic controller,to implement each function's swith in the process of placement.
