摘 要

振动压路机是众多工程施工设备中的一种，其主要要用于压实各种土壤、碎石块以及各种沥青混凝土等。在公路施工中，主要用于路基、路面的压实，是修路施工中不可缺少的压实设备。根据振动压路机的结构特点、工作原理、操作方法和主要用途等的不同，可以分为不同的种类。按振动轮内部结构的不同可分为：振动、震荡和垂直振动。按振动型式又可分为：单频单幅、单频双幅、双频多幅、无级调频调幅等。由此可见，振动轮是振动压路机的核心。

我国的振动压路机的研究已经相对成熟，但是与国外发达国家相比仍然有很大的差距，本文主要研究的就是压路机振动轮的设计。

  本设计简要介绍了振动压路机的发展概况、振动机构、激振器的结构、偏心块的设计与计算和减振块的设计计算，轴的设计与校核，轴承的寿命计算。

The YZ8H vibratory roller design

ABSTRACT

The vibratory roller is one of the important construction equipments for compaction of soil, aggregates, asphalt and concrete. In highway construction, it is used in the compaction of the roadbed and act as an indispensable road construction. The 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.

This article introduces the design of vibration roller development, vibration mechanism, vibration wheel configuration power calculation, the exciter eccentric block type, the design and calculation of vibration system, calculation of stiffness and damper design, shaft design and verification, selection and the service life of the bearing calculation.

KEY WORDS: vibratory roller, design, Vibration exciter
