混合动力轻型客车离合器总成三维设计(含CAD图,CATIA三维图)(开题报告,论文说明书10000字,CAD图6张,CATIA三维图)
摘  要
本文的研究目标是混合动力轻型客车离合器，通过建立离合器总成并使用激光数字扫描法和建立成三维实体模型并进行相关工作图设计完成本次课题的研究内容。
本次课题研究，我们采用逆向工程设计，逆向工程是对零件的再现过程，通过对现有零件进行研究，可以逆向得出该零件的一些数据信息和组织特性。
现有的离合器组成部件有：扭转减震器夹具、离合器壳、膜片弹簧、从动盘、分离拨叉与分离轴承等。我们首先对这些零件用3D扫描仪进行扫描，经过处理后得到点云数据，然后用三维画图软件（如CATIA）将点云数据导入并进行建模和装配处理。
三维模型虽然直观明了，但我们无法从中获得尺寸数据，所以接下来的工作要将三维模型转换为工作图。我们可以用CATIA软件先对三维图进行投影和简单的标注，再将二维图导入CAD软件进行详细的标注和修改。
本文通过对混合动力轻型客车离合器进行三维建模和研究，了解了离合器的设计过程，为进一步改进离合器提供了依据。

Three Dimensional Design of Clutch Assembly for Hybrid Light Bus
Abstract
The paper takes the hybrid light bus clutch as the research object,it establish a clutch using the method of laser scanning and set up a three-dimensional entity model and design relevant Working drawings to complete this topic research content.
In the research, we use reverse engineering design.Reverse engineering is the process of the reproduction of the parts. Through the research of the existing parts, it can get some of the parts of the data information and organizational characteristics.
The main components of the clutch are: driven plate, clutch shell, torsion shock absorber, diaphragm spring, split fork and separation bearing.We first use the 3D laser scanning technology to scan the components of the clutch and get point cloud data.Than we use three-dimensional drawing software CATIA to scan data processing and three-dimensional modeling.
Although the three-dimensional models are intuitive and clear,we can not get the size of the data.So the next work is converting the three-dimensional model to work drawings. We can use the software of CATIA to carry on the projection and the simple annotation to the three-dimensional map first.Then we import the two-dimensional chart to the software of CAD to carry on the detailed annotation and the revision.
