1 吉林大学本科(自考)毕业论文(设计) 题目汽车四轮定位及其检测系统研究学生姓名班级汽车检测与维修学院专业汽车检测与维修指导老师摘要随着汽车工业的高速发展,我国汽车拥有量越来越多,而且每年都呈上升趋势, 在这种新形势下,汽车四轮定位在汽车检测与维修行业逐渐凸显出其重要性。伴随着汽车四轮定位设备的不断改善,准确性不断的提高,汽车四轮定位使汽车使用的安全性得到足够的保障。汽车四轮定位将在现代汽车行业成为不可或缺的技术,随着技术的不断改进,使得检测简单易懂,具有较高的社会经济价值。本文在传统的汽车转向轮定位理论的基础上,进一步阐述汽车四轮定位原理;推导出汽车四轮定位参数的空间几何关系;通过对汽车四轮定位理论及汽车四轮定位仪对定位参数的检测原理、系统构成等方面进行理论研究,提出正确使用四轮定位仪的注意事项、基本步骤、方法。结合试验分析汽车四轮定位测试系统在汽车检测中的运用以及总结出定位参数之间的联系。关键词:四轮定位;检测原理;测试系统;运用 Abstract Along with the rapid development of the vehicle industry, our country vehicle capacity is getting more and more, moreover every year assumes the trend of escalation, under this kind of new situation, the four-wheel alignment highlights its importance in the automobile testing and the service profession gradually. Following the uninterrupted improvement of the equipment of the four-wheel alignment , accurate unceasing enhancement, the four-wheel alignment make the security of the automobilism to obtain the enough safeguard. Four-wheel alignment would e the necessary technique in modern car profession, along with technique of continuously improvement, it make examination simple and easy understand, so it have higher of society economy value. This article is based on traditional automobile steering wheel positioning ’s theory, to expatiate the principle of the four-wheel alignment further ; and infers the four-wheel alignment the spatial geometry relations of the parameters ; Through to research the fundamental of the four-wheel-positioning and positioning equipment , investigate testing principle of positioning parameter , system constitution and soon, bring forward matters needing attention,the basic step, the method correctly of make use of four-wheel alignment equipment .Integrate the experimentation to analyzing the testing system of the four-wheel alignment ’s exertion in testing of vehicle and sum up the relation of location parameters Key words : four-wheel alignment ; automobile structure ; testing principle ; exertion 目录第一章绪论........
