轻型货车汽车前后悬架的设计+文献综述

摘要在车辆工程中，悬架对车辆的乘坐舒适性和操纵稳定性的提高起着关键作用。本文主要介绍悬架的基本结构和功能，研究轻型货车的前后悬架设计分析方法。
本设计前悬架采用麦弗逊式独立悬架，后悬架采用纵置板簧式非独立悬架。然后对悬架的性能参数进行选择。在选择完基本参数后，对悬架的弹性元件（前悬架为螺旋弹簧。后悬架为钢板弹簧）进行设计计算，包括刚度和强度等的校核，使设计的弹簧能满足设计的偏频要求。之后设计前独立悬架的导向机构，设计包括侧倾中心、纵倾中心以及下控制臂的位置等。为前、后悬架匹配减振器，计算减振器的尺寸，并且验算减振器是否满足强度要求。最后，为了满足汽车不足转向性能要求，为前悬架匹配了一个横向稳定杆，提高它的侧倾刚度。8780

Title    vehicle suspension design
Abstract
In the vehicle engineering,the suspension system is the key component to improve the riding comfort and handling stability.This article is mainly about to introduce basic construction and function of suspension. and study the method of designing a light truck’s front and back suspension.
In this design, we use McPherson type front suspension,Back suspension’s steel spings.and then, we choose the suspension’s property parameters. After these basic parameters were chosen, we comes on to calculate the spring of the suspension,(spiral spring in front suspension, leaf spring in back suspension),and the calculation including checking both the springs` striffness and strength, as to make the spring designed to meet the demand of frequency. And next comes to design the control bars of the front independent suspension, it contains to design the roll center height an trim center height and the locations of the main controlbar.Then,we design shock absorbers to match with the front and the back suspension, including calculate the size of the absorbers and also check the absorbers to see if it meets the demand of strength. Lastly, in order to meet the property demands of car’s under steer speciality, it designs a anti-roll bar to improve the front suspension’s roll angular rigidity.
