北京理工大学珠海学院 2020 届本科生毕业设计比亚迪 F3 轿车悬架设计比亚迪 F3 轿车悬架设计摘 要随着国民生产总值与现代工业的发展，汽车成为了人们出行的一个重要方式，随着生活质量提升，对汽车的舒适性、行驶质感、操控性等性能的眼光也日渐挑剔，故对悬架的操控性、乘坐舒适性的要求也逐渐严格。因此本设计以尽可能满足人们对悬架的需求为目标，在比亚迪 F3 的基础上对后悬架进行设计，与此同时还要保证设计的悬架安全可靠。本论文包括了悬架发展历史以及基本原理的介绍、后悬架的选型、独立悬架导向机构的设计、螺旋弹簧以及减振器的设计。此外设计中还包含对双横臂悬架中主要部件的 CATIA 建模以及 CAD 二维图，共计三张。关键词：双横臂悬架、独立悬架、螺旋弹簧、减震器北京理工大学珠海学院 2020 届本科生毕业设计Suspension design of BYD F3AbstractWith the improvement of GDP and auto’s industry, automobile have becoming an important way for people to travel. With the development of the standard of life, people are becoming critical of the comfort, driving texture, handling and other performance of the automobile, so the requirements for the handling and riding comfort of the suspension are 北京理工大学珠海学院 2020 届本科生毕业设计increasingly strict. Therefore, this design is in order to satisfy the requirements of people imagine about the suspension. On the basis of BYD F3, the rear suspension is designed, and at the same time, insurance the designed suspension is safety.This paper includes the development history of suspension, the introduction of basic principles, the selection of rear suspension, the design of independent suspension guiding mechanism, the design of coil spring and shock absorber.In addition, the design also includes the CATIA modeling and CAD two-dimensional drawing of the main components of the double wishbone suspension, a total of three.Key words: double wishbone suspension, independent suspension guide mechan...
