摘 要 振动压路机是工程施工的重要设备之一，用来压实各种土壤、碎石料、各种沥青混凝土等。在公路施工中，多用在路基、路面的压实，是筑路施工中不可缺少的压实设备。根据振动压路机工作原理、结构特点、操作方法和用途等的不同，有不同的分类方法。按振动轮内部结构可分为：振动、震荡和垂直振动。其中振动又可分为：单频单幅、单频双幅、单频多幅、多频多幅和无级调频调幅。可见，振动轮是振动压路机的核心工作机构。 我国的振动压路机研究已经接近成熟，但是与国外相比仍有很大的差距，本文意在研究压路机振动轮的相关参数和结构，使其能够在工作状态达到效率最大化，能够缩小和国外的研究差距。 本文在理论分析和计算的基础上，完成了8T双钢轮振动压路机的振动轮的设计，在激振结构上采用了振动轴加上偏心块的结构，能够产生双频双幅的振动形式，减振系统采用橡胶减振器，利用更加简化的单自由度振动数学模型，推导出达到最大减振效果时减振系统总的动刚度，作为橡胶减振器设计的依据，并对压路机进行了稳定性分析。 关键词：振动压路机，振动轮设计，振动轴，偏心块，激振力，减振 ABSTRACT The vibratory roller is one of the important construction equipment for compa- -ction of soil, aggregates, asphalt and concrete. In highway construction,it is used in the compaction of the roadbed and is an indispensable road vibratory roller can be classified depending on the vibratory roller’s working principle, the structural characteristics, methods of operation and use .It can be divided through the internal structure of the wheel vibration: vibration, shock and vertical vibration. Whele vibration can be divided into single-frequency single, single-frequency double-width, single-frequency multiple pieces of multi-frequency and stepless AM FM. So, the vibrating drum is the core of vibratory roller . Our vibratory roller studies have been approaching maturity, but there is still a big gap compared with foreign countries, this article is intended to study the relevant parameters and structure of the roller wheel vibration, to enable them to maximize efficiency in working condition, can be reduced and abroadresearch gaps. On the basis of theoretical analysis and calculation ,I complete a of 8T double drum vibratory roller wheel vibration design. Vibration excitation structure with a shaft and eccentric structure, can produce a dual-frequency vibration in the form of double width,Rubber shock absorber damping system is to use a more simplified single degree of freedom vibration model is derived for maximum vibration damping effect of the total system whe
