吉普指南者悬架系统设计与仿真北京理工大学珠海学院 2020 届本科生毕业设计吉普指南者悬架系统设计与仿真摘 要悬架是影响汽车操纵稳定性和行驶平顺性的重要部件，其开发设计水平对其作用的影响尤为重要，传统的悬架设计不仅周期长，而且成本也高。而悬架设计加入电子样机技术对汽车悬架进行动态仿真是一种避免浪费人力物力的有效方法。本文首先论述了悬架的发展过程和动态仿真的发展现状，针对麦弗逊式悬架进行结构设计，对悬架系统的主要参数计算校核，利用 CATIA 软件的零件设计模块建立简化的三维模型，将建模的零件导入装配设计模块中进行装配。在这个基础上，对装配图的主要部件施加合理的约束、运动副和驱动命令，完成麦弗逊式悬架的动态仿真，再在 DMU 运动机构基础上对仿真进行动态干涉，创建关键部件的包络体。并且在仿真中证明在行驶过程中，车辆跳动极限和转向极限范围内保证汽车行驶的安全性及操纵稳定性。关键词：麦弗逊式悬架 CATIA 软件 动态仿真北京理工大学珠海学院 2020 届本科生毕业设计Design and Simulation of jeep guider suspension systemAbstractSuspension is an important part that affects vehicle handling stability and ride comfort. Its development and design level is particularly important for its role. The traditional design not only has a long cycle,but also has high cost. It is an effective way to avoid wasting human and material resources to add electronic prototype technology into suspension design to carry out dynamic simulation of automobile suspension.This paper first discuss the development process of suspension and the development status of dynamic simulation, designs the structure of McPherson suspension, calculates and checks the main parameters of suspension three-dimensional model with the part design module of CATIA software,and import the modeled parts into the assembly design module for assembly. On this basics, the main components of the assembly drawing are subject to reasonable constraints and driving are command to complete the dynamic simu...
