EA113 汽油机曲柄连杆机构设计 姓 名: 专 业:机械设计制造及其自动化 指导教师:摘 要:本文以捷达 EA113 汽油机的相关参数作为参考,对四缸汽油机的曲柄连杆机构的主要零部件进行了结构设计计算,并对曲柄连杆机构进行了有关运动学和动力学的理论分析与计算机仿真分析。
首先,以运动学和动力学的理论知识为依据,对曲柄连杆机构的运动规律以及在运动中的受力等问题进行详尽的分析,并得到了精确的分析结果。
其次分别对活塞组、连杆组以及曲轴进行详细的结构设计,并进行了结构强度和刚度的校核。
再次,应用三维 CAD 软件:Pro/Engineer 建立了曲柄连杆机构各零部件的几何模型,在此工作的基础上,利用 Pro/E 软件的装配功能,将曲柄连杆机构的各组成零件装配成活塞组件、连杆组件和曲轴组件,然后利用 Pro/E 软件的机构分析模块Pro/Mechanism,建立曲柄连杆机构的多刚体动力学模型,进行运动学分析和动力学分析模拟,研究了在不考虑外力作用并使曲轴保持匀速转动的情况下,活塞和连杆的运动规律以及曲柄连杆机构的运动包络。
仿真结果的分析表明,仿真结果与发动机的实际工作状况基本一致,文章介绍的仿真方法为曲柄连杆机构的选型、优化设计提供了一种新思路。

First motion laws and stress in movement about the crank link mechanism areanalyzed in detail and the precise analysis results are obtained. Next separately to the pistongroup the linkage as well as the crank carries on the detailed structural design and hascarried on the structural strength and the rigidity examination. Once more applysthree-dimensional CAD software Pro/Engineer establishing the geometry models of allkinds of parts in the crank link mechanism then using the Pro/E software assemblingfunction assembles the components of crank link into the piston module the connecting rodmodule and the crank module then using Pro/E software mechanism analysis modulePro/Mechanism establishes the multi-rigid dynamics model of the crank link and carrieson the kinematics analysis and the dynamics analysis simulation and it studies the pistonand the connecting rod movement rule as well as crank link motion gear movementenvelopment. The analysis of simulation results shows that those simulation results are meetto true working state of engine. It also shows that the simulation method introduced here canoffer a new efficient and convenient way for the mechanism choosing and optimized designof crank-connecting rod mechanism in engine.Keywords: Engine;Crankshaft-Connecting Rod Mechanism;Analysis of Force;Modeling of Simulation;Movement Analysis;Pro/E II 目 录题目 Ⅰ摘要 ⅠAbstract Ⅱ1 前言 11.1 选题的目的和意义 11.2 国内外的研究现状 11.3 设计研究的主要
