摘要本文设计的悬架系统相比其他越野车有更为严苛的性能要求。本文根据特种越野车的总体设计，通过ADAMS/Car对特种越野车的悬架系统性能和重要零部件的受力进行仿真分析，评价设计方案。本文主要研究内容如下：
（1）悬架系统的总体设计方案和模型的建立。
（2）弹性元件与导向机构的设计。本文所设计前后悬架系统均采用多连杆非独立悬架。其中后悬架系统导向机构采用了特殊的交叉纵臂结构。
（3）悬架系统平顺性分析。平顺性分析主要依靠ADAMS/Car进行仿真分析。
（4）分析多连杆结构运动干涉并优化。本文通过ADAMS/Car对杆系重要连接点受力进行分析，从而得出多连杆结构的运动干涉并作出相应的优化。
    本文对于特种越野车悬架的设计对特种越野车的设计工作提供借鉴参考。24163

Title      Special SUV Suspension Design  
Abstract
Special SUV is the SUV that working in unique situations,such as open-air construction sites and mine tampings. Special SUV are mainly working on off-road which are really poor. Therefore, the suspension system of special SUV need to satisfy harder requirement than others. Nowadays, native market is occupied by foreign companies. With the increasing demand, the research on the suspension of special SUV has become more and more important.
  According to the overall design, writer takes use of ADAMS/Car to evaluate the suspension model and main parts of it. The major content:
(1) The overall design of the suspension and build the dynamic model.The natural frequency of the fore and rear suspension is 1.605Hz and 1.851Hz. It is beneficial to the ride comfort.
(2) Spring and link. The fore and rear suspensions of the special SUV are both muti-link dependent suspension with helical spring. And the rear suspension uses the special crossing longitudinal control arm to elevate the bump and rebound travel.
(3) Suspension ride comfort analysis. Taking use of the ADAMS/Car to analyze the ride comfort.
(4) The analysis and improvement of the distribution. Writer analyze the distribution according to the character of the multi-link and the force at the important point to improve the suspension through ADAMS/Car.
  The design in this essay mainly concentrate on the improvement of the ride comfort and the bump and rebound travel. The research can be helpful to the design of the special SUV.
Keywords  Special SUV, multi-link dependent suspension, helical spring, crossing longitudinal control arm
