1、 本科生毕业设计（论文） I 摘 要 随着汽车工业的发展，人们对汽车的乘坐舒适性和安全性的要求逐渐提高，因此对汽车的悬架系统和减振器也提出了更高的要求。本次设计题目是CA1091 轻型货车的前后悬架系统设计。 所设计悬架系统的前悬架采用钢板弹簧非独立式悬架。后悬是由主副簧组成，也是 钢板弹簧非独立式悬架 ，然后对主要性能参数进行确定。在前悬的设计中首先设计了钢板弹簧，包括弹簧断面形状的选择， 主要参数的确定，材料和许用应力的 校核 ，和方案布置的设计；还 有减振器的选择。在后悬架系统设计中主要对主副钢板 弹簧进行了设计 。 最后采用 MATLAB 软件对悬架系统的平顺性进行了编程分析，目的是判

2、断所设计的悬架平顺是否满足要求。结论 是没有不舒适性。 因而对提高汽车的动力性、经济性和操纵稳定性是有利的。 关键词： 悬架设计；钢板弹簧；平顺性；货车 本科生毕业设计（论文） II Abstract With the development of the Automobile industry, people have been promoting the requirement for the safety and ride comfort quality of the vehicle. As a result, there is a higher demand on the suspen

3、sion and the shock absorber system of the vehicle. The title of this thesis is the design of front and rear suspension systems of CA1046 truck. The front suspension system is the leaf spring, dependent suspension. The rear suspension system consists of the main spring and the helper spring and it is

4、 also the leaf spring, dependent suspension. In the procedure of the design we made certain the structural style of the suspension system in the first, then we made certain the main parameters. In the design of the front suspension we designed the leaf spring firstly, including the selection of sect

5、ion shape of leaf spring, made certain the main parameters, material and allowable stress and the design of scheme , moreover the design of shock absorber. In the design of rear suspension we carried out the design of the main spring and the helper spring. In the final design stage, the MATLAB softw

6、are is used to analyze the ride comfort of the suspension system by programming. The aim is whether suspension ride quality meets to the performance requirement. The results indicate that there is no uncomfortableness for the car on road. Therefore, it is helpful for the dynamical, economical and handling performances of the vehicle.
