摘 要

操纵稳定性是汽车的重要使用性能之一,它不仅影响到汽车驾驶的操纵方便程度,而且也是决定高速汽车行驶安全的一个重要性能,被称为“高速车辆的生命线”。因此操纵稳定性日益受到人们的重视。但是传统的研究分析方法已无法满足现代汽车的研究要求,现在虚拟样机技术作为一项新的产业技术,己经开始应用到各个领域。本文正是利用动力学仿真软件ADAMS研究探讨悬架系统对操纵稳定性的影响。

本文以汽车的前悬架系统为研究对象,应用ADAMS软件对汽车做仿真优化分析。第二章和第三章详细的介绍了汽车操纵稳定性在国内外发展状况及研究成果及ADAMS软件。然后利

用ADAMS/Car模块建立汽车的前悬架系统并对该系统进行模拟仿真分析 。

Abstract

Handling and stability is one of the important performance of the car, it not only affects the ease of manipulation of motorists, but also determine the performance of an important high-speed cars with security, known as \increasing handling stability people's attention. But the traditional analysis methods have been unable to meet the research requirements of modern car, and now virtual prototype technology as a new industrial technology, had begun applied to various fields. This article is the use of dynamic simulation software ADAMS study investigated the effect of steering stability of the suspension system.

In this paper, the car's front suspension system for the study, application software ADAMS simulation and optimization analysis of automobile do. The second and third chapters detailed description of the vehicle handling and stability at home and abroad and the research and development of ADAMS software. Then use ADAMS / Car module builds the front suspension system of the vehicle and the system simulation analysis.

Keywords ADAMS / CAR car front suspension kinematics simulation steering stability
