(完整版)SUV轿车悬架系统设计说明书毕业设计论文Word格式.docx

1、悬架系统也是为了适应发展当前的这种实际的需要而设计。本次设计主要研究SUV轿车的前、后悬架系统的结构设计。前悬架采用目前较流行的麦弗逊式独立悬架系统，后悬架采用舒适性较好的二连杆式非独立悬架。前、后悬架的减振器均采用双向作用式筒式减振器。这种结构的设计，有效的提高了乘座的舒适性和驾驶稳定性。在此次设计中还进行了悬架参数的确定、弹性元件的设计计算、导向机构和横向稳定杆的结构计算及强度校核。而且，采用Matlab 软件对悬架系统的平顺性性进行了编程分析，论证了该系统设计方案的合理正确性，能够满足工程实际的需要。本设计对于提高汽车行驶平顺性、操纵稳定性等问题具有一定的的实际意义。此外对于汽车生产企业
