摘要
本文以195柴油发动机的相关参数作为参考,对195柴油发动机的活塞连杆组机构的主要零部件进行了结构设计计算,并对活塞连杆组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,对活塞连杆组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:Solidworks建立了活塞连杆组各零部件的几何模型,在此工作的基础上,利用Solidworks软件的装配功能,将活塞连杆组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Solidworks软件的机构分析模块,建立活塞连杆组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活塞连杆组的运动包络。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活塞连杆组的选型、优化设计提供了一种新思路。

ABSTRACT
This article refers to by the Jeeta 195 gasoline engine’s related parameter achievement, it has carried on the structural pution for main parts of the crank link mechanism in the gasoline engine with four cylinders, and has carried on theoretical analysis and simulation analysis puter in kinematics and dynamics for the crank link mechanism.
First, motion laws and stress in movement about the crank link mechanism are analyzed in detail and the precise analysis results are obtained. Next separately to the piston group, the linkage as well as the crank carries on the detailed structural design, and has carried on the structural strength and the rigidity examination. Once more, applys three-dimensional CAD software Solidworks establishing the geometry models of all kinds of parts in the crank link mechanism, then useing the Solidworks software assembling function assembles ponents of crank link into the piston module, the connecting rod module and the crank module, then using Solidworks software mechanism analysis module (Pro/Mechanism), establishes the multi-rigid dynamics model of the crank link, and carries on the kinematics analysis and the dynamics analysis simulation, and it studies the piston and the connecting rod movement rule as well as crank link motion gear movement envelopment. The analysis of simulation results shows that those simulation results are meet to true working state of engine. It also shows that the simulation method introduced here
