摘要轮胎压路机是一种利用充气轮胎而对被压材料进行压实的一种重型机械,种类繁多,适应性强,应用广泛。轮胎产生的作用力方向除了向着轮胎的行驶方向之外，还沿着轮胎的纹理横向。正是由于它产生的压实力可以向各个方向全面地传递到被压材料上,被压材料能够得到最大的实密度。橡胶轮胎的"揉搓效果",也会提高路面的压实效率，路面更加严实和平整。73830

    在今天，压路机作业的工程质量也要有越来越高的质量。为了将被压实材料能够得到均匀而严密的压实效果,轮胎压路机的悬挂装置也被提出了特殊的要求。

    新型油气悬挂的出现无疑是一大亮点。在传统机械的基础上，一是包括了减震器和弹性元件，二是自带横向稳定器的作用：因为它可以联通左、右油路，并且加大侧倾角的刚度。简化了复杂的结构，在悬挂结构中脱颖而出。

    所以本篇论文旨在介绍油气悬挂系统的分类及特点,对其进行数学模型的建立以及参数的描述,编制计算机程序对其进行计算机仿真,对其非线性特性进入深入研究,尤其研究蓄能器和悬挂缸的参数设置对其性能的影响，找到最佳参数，优化设计。

Design of suspension system in tire roller of YL25

Abstract The tire road roller is a kind of heavy machinery, which is used to press the compacted material with the pneumatic tire. It has many kinds, strong adaptability and wide application. The force direction of the tire is in addition to the direction of the tire, and also along the tire texture. It is precisely because of its ability to produce the compaction force can be transmitted to the various directions in the material, the material can be the maximum density. Rubber tire "rubbing effect", will increase the efficiency of compaction of the road, the road more tight and smooth. 

Today, the project quality of road roller work also has to be more and more high quality. In order to be compacted material can get uniform and tight compaction effect, the suspension device of the tire road roller is also put forward special requirements. 

The emergence of a new type of oil and gas suspension is undoubtedly a major bright spot. On the basis of traditional machinery, one is including the shock absorber and elastic components, the two is the role of lateral stabilizer: because it can link the left and right oil circuit, and increase the stiffness of the lateral angle. Simplify the structure of the complex, in the suspension structure. 

So this paper aims to introduce oil gas suspension the classification and characteristics of the system, and the of mathematical model is established and the parameters are described, the computer program of the of computer simulation, into the in-depth study to the nonlinear characteristics, especially for the research on energy storage device and suspension cylinder parameters setting influence on its performance, and find the best parameters, optimization design.
