摘 要
随着人们对汽车驾驶的操纵性和乘客乘坐舒适性要求越来越高，以及电子技术的日渐成熟，现代汽车悬架系统也将其技术大量应用于其中，使悬架不同的路面和行驶状态作出不同反应是电子控制悬架系统的最大优点。乘坐舒适性达到令人满意的状态是人们对现代汽车的基本要求，而对于驾驶者来说，汽车的操纵稳定性则显得尤为重要。XX-400的悬架系统采用的是目前最先进的主动式空气弹簧悬架，在不同的行驶状况下(路况)自动控制弹簧刚度、减振器阻尼力和车高，以达到抑制加速时后坐、制动时点头、转向时侧倾等汽车行驶状态的实时变化，从车身的稳定性能方面来改善乘坐的舒适性和驾驶者的操纵的稳定性。现代汽车教育行业发展迅猛，传统的修理厂师徒制的教授已经不能满足我国目前汽车修理行业的发展，汽车悬架装置检测台的设计已经迫在眉睫，为配合汽车维修教育、培训以及研究需求所设计了本次的检测台架，对XX-400悬架的工作原理，传感器、执行器的故障分析给出直观的表现，不论对于初次学习汽车悬架的在校学生还是有经验维修企业员工都有非常直接有效的帮助，检测台结构合理并尽可能的考虑汽车教学实际要求，主要由悬架系统等实物组成，并配置了多功能控制柜/显示柜，目的是为了适应教学要求。
XX-400悬架系统的结构组成在设计说明书进行了最为基本的讲解，对LS400悬架系统的基本控制原理进行了逐一分析，XX-400悬架系统检测台的总体设计方案是此设计说明书的最主要也是最核心的内容。计划方案包罗检测台台架的设计，检测台面板的设计、检测台面板控制图的设计、故障点的设计等。 最后，还对检测台的使用和操作过程做了介绍。

ABSTRACT
Along with the people to the vehicle's handling and riding comfortability requirements more and more high, and electronic technology, the modern automobile suspension system will also be the technology has been applied to the suspension, the different road and driving conditions make different reaction is the biggest advantage of electronic control suspension system. The ride comfort of a satisfactory state is one of the basic requirements for modern car, the driver, the vehicle handling stability is the most important. Electronic controlle. Electronic controlled suspension system Toyota Lexus lS400 is active air spring suspension is currently the most advanced, in different driving conditions (Lu Kuang) spring stiffness, damping force and high automatic control, to achieve the real-time change of acceleration, braking recoil suppression nod, steering roll of the driving state of the vehicle handling and stability, from the aspects of the body stability to improve ride comfort and driver. The modern automobile education industry is developing rapidly, the traditional repair factory mentoring professor has been unable to meet the development of our country's current auto repair industry, design of automotive suspension test rig has been imminent, with auto repair education, training and research needs of the design of the experimental platform for this time, the work principle of Lexus LS400 control suspension analysis, gives an intuitive display fault sensor, execution, regardless of the initial study of automobile suspension students or staff experience repair enterprises are very direct and effective help, experiment table structure is reasonable and possible given the car the practical requirements of teaching, mainly by the suspension system and other physical composition, and the configuration of the multi function control cabinet / display cabinet, the purpose is to adapt to the requirements of teaching.
