文档介绍：轻型载货汽车后悬架钢板弹簧设计
摘要
悬架是保证车轮或车桥与汽车承载系统之间具有弹性联系并能传递载荷、缓和冲击、衰减振动以与调节汽车行驶中的车身位置等有关装置的总称。悬架最主要的功能是传递作用在车轮和车架之间的一切力和力矩，并缓和汽车行驶过不平路面时所产生的冲击，衰减由此引起的承载系统的振动，以保证汽车行驶的平顺性。
本文讨论了汽车悬架的开展现状，对悬架的结构形式进展简单介绍，对影响悬架运动的各种因素进展分析，本文通过传统的设计计算方法和计算机技术相结合，以依维柯欧霸轻卡为原型车，详细设计计算了渐变刚度钢板弹簧后悬架。
文中首先介绍了悬架系统领域的研究与设计与其开展现状和趋势；其次详细概述了悬架系统对汽车平顺性和操纵稳定性的影响；再次着重阐述了钢板弹簧悬架设计的详细步骤和设计要求，各主要零部件结构的选型与计算；板簧弧高与曲率半径的计算，材料强度、刚度的验算、校核；减振器的选取。

DESIGN OF LIGHT TRUCK
SUSPENSION WITH LEAF SPRING
ABSTRACT
Suspension involves some related ponents, which exist to guarantee elastic contact between wheels or axle and the carrying system. It also has a great contribution in transferring the load, cushioning the impact, attenuating vibration, and regulating the position of the body of the running car. Apart from the transformation of force and moment between wheels and frame, it helps cushion the impact when uneven road surface is encountered, undermine the following vibration of carrying system, as a result, provide a great possibility of smoothly running.
This paper discusses the current development of vehicle suspension, gives a brief introduction of the structural form of suspension, analyze factors which have influence on suspension movement. This article through the traditional design calculation method and puter technology, bining
with IVECO Light Truck Tire as the prototype, the car design calculation after gradient stiffness &leaf spring suspension.
This paper firstly introduces the suspension system research and design and development status quo and tendency; Secondly detailed overview of the suspension system and manipulation stability fort ability influences; Introduces emphatically the leaf spring again suspension design processes of the ship unlades and design requirements, the structure of the main parts selection and calculation, leaf-spring curvature, material strength, stiffness checking and checking, shock absorber selection and installation Ang
