摘 要:本次设计主要从汽车悬架当中的钢板弹簧入手，去深入的了解并且自己动手去设计一个完整的钢板弹簧悬架。自己查阅了不少关于汽车底盘设计的相关书籍，与指导老师探讨设计以及计算的各个细节，然后设计了一副完整的悬架，再经过数次的修改，最终完成了了一个较为完善的悬架。首先对汽车钢板弹簧的结构方案进行论证,根据设计给定的四个参数对整车进行总体设计，包括整车的尺寸参数、质量性能参数和性能参数，在选择这些参数的时候可以通过国家标准以及相关的经验参数得到,最后对细节部分如卷耳形状，弹簧片截面形状等的最终确定。然后对选取的细节部分进行理论计算、验算是否符合其工作强度要求并且最终确定其具体参数，如曲率半径,片厚.片宽.片数等,并且以此参数进行制图。根据计算的参数，再选取与之配合的标准件。最后对组装好的悬架系统对汽车的稳定性的影响进行理论计算以及评估。经过对细节的审核以及修改，最后对参照了重庆钢板弹簧厂的工艺要求，根据自己设计的板簧的特点，编写了工艺要求。板弹簧的制造是由一板材进行冲裁，卷耳，淬火，回火，喷丸等工艺过程得到个片板簧，再对加工好的板簧进行组装而成。

ABSTRACT:This design mainly from the automotive leaf spring suspension which start to understanding yourself and to design a complete leaf spring suspension. Their access to a lot about the car chassis design related books, and instructor discuss all the details of the design and the calculation and design of a complete suspension, and then after a few modifications, the final completion of a more perfect hanging aircraft. First, the structure of the automotive leaf spring demonstration programs, according to the design given four parameters for the overall design of the vehicle, including the vehicle's dimensions, quality, performance parameters and performance parameters, the choice of these parameters when you can pass the national standard and related empirical parameters to get the last part to details such as volume ear shape, spring-sectional shape of the final OK. Then select the details of the theoretical calculations, checking compliance with the strength requirements of their work and ultimately determine the specific parameters, such as the radius of curvature, slice thickness. Piece wide. Plate number, etc., and this parameter mapping. According to the calculation of the parameters, and then select a complementary standard parts. Finally, the assembled suspension system of the car stability theoretical calculations and assessments. After a detailed review and modify, and finally the reference leaf spring factory in Chongqing process requirements, according to their own design characteristics of the leaf spring, the preparation process requirements. Manufacture of the plate spring by a sheet metal punched out, the Word, quenching, tempering, shot blasting process to obtain a sheet spring, and then the processed leaf spring assembled.
Key words: plate spring suspension structure argument parameter determination process requirements
