文档介绍：摘要
发动机是机器的“心脏”,它是机器最重要的部分,随着科学技术的飞快发展,国际之间关于发动机的竞争也也越来越激烈,所以对发动机的研究具有重要的科学意义。本文的设计方法采用常规手段与微机辅助相结合。
在设计中首先查阅中外资料,了解发动机的结构及工作原理,确定本文所设计的发动机结构。本文主要针对摩托车发动机的缸体、连杆、活塞等零部件进行设计与三维建模。缸体的设计主要内容包括气缸体的结构设计、材料的选择和参数设计,缸体是发动机零部件中重要的零部件,所以在本文中还对缸体进行加工工艺规程进行设计从而确定加工工艺路线。连杆的设计的主要内容是连杆的结构、连杆承受的载荷和连杆的位移等。活塞设计的主要内容是活塞的材料的选择、主要参数和活塞的运动分析。本文还利用UG软件完成了对缸体、活塞、连杆等零部件的三维建模以及零部件之间的装配,并且完成了零部件三维向二维工程图的转换以及对装配图进行运动仿真分析。

Abstract
The engine is the "heart" of the machine, it is the most important part of the machine. With the fast development of science and technology, petition is also more and more fierce among countries, so it has important scientific significance for engine research. The design method of this paper bined conventional means puter-aided.
In order to determine the design structure of engine, this paper has consulted the Chinese and foreign information and understood the structure and working principle of the engine. This paper focuses on the design and 3D modeling of motorcycle engine cylinder block, connecting rod, piston and other parts. The design of cylinder mainly includes cylinder block structural design, materials selection and parameter design, the cylinder is the important parts of the engine parts, so this article pleted the design of cylinder planning process in order to determine route. The design of connecting rod mainly includes the structure of the connecting rod, bear the load and connecting rod displacement. The design of piston mainly includes piston material selection, analysis of the main parameters and the movement of the piston. This paper also uses UG software plete the three-dimensional modeling of cylinder, piston, connecting rod and assemble of parts. Then this paper pleted the conversion of parts of the three-dimensional to two-dimensional drawings and motion simulation analysis for assemble.
Key words: motorcycle engine; UG; three-dimensional modeling; motion simulation
