振动压路机是利用其自身的重力和振动压实各种建筑和筑路材料。适宜压实各种非粘性土壤、碎石、碎石混合料以及各种沥青混凝土。在振动压路机作业过程中，由于振动压实的需要，经常需要调节振动轮振幅。下面小编就带大家一起来了解一下振动压路机的工作原理。
Vibratory roller uses its own gravity and vibration to compact various building and road building materials. It is suitable for compacting all kinds of non cohesive soil, gravel, gravel mixture and all kinds of asphalt concrete. In the process of compaction, the vibration amplitude of the roller needs to be adjusted. Let's take you to understand the working principle of vibratory roller.
当振动压路机激振器固定偏心块与振动轴固接在一起，另一动偏心块空套在振动轴上。当振动马达正反转时，则产生了两种不同的偏心块叠加方式，能得到两种不同的静偏心矩。激振器振动调幅机构振动轴顺时针旋转时，动偏心块与固定偏心块静。偏心距相加，从而产生大振幅；振动轴逆时针旋转时， 动偏心块与固定偏心块静偏心距相减，从而产生小振幅。
When the vibration roller exciter is fixed, the eccentric block is fixedly connected with the vibration shaft, and the other moving eccentric block is sleeved on the vibration shaft. When the vibration motor is in the forward and reverse direction, two different superposition modes of eccentric blocks are generated, and two different static eccentric moments can be obtained. When the vibration shaft of the vibration amplitude modulation mechanism of the exciter rotates clockwise, the dynamic eccentric block and the fixed eccentric block are static. The eccentricities are added to produce large amplitude; When the vibration shaft rotates counterclockwise, the static eccentricity of the dynamic eccentric block and the fixed eccentric block is subtracted, resulting in small amplitude.
与自行式振动压路机的工作原理相同，拖式振动压路机也是依靠自重和激振力迫使被压实材料做垂直强迫振动，急剧减小土壤颗粒间的内摩擦力，达到压实土壤的目的；激振力的大小可以根据需要进行调整。不同的是拖式压路机不能行走，通过其他牵引车拖动才能行走和压实。根据不同的压实厚度和材料可选择不同的碾压轮质量或静力或振动。
The working principle of the self-propelled vibratory roller is the same as that of the self-propelled vibratory roller. The towed vibratory roller also forces the compacted material to make vertical forced vibration by relying on its own weight and exciting force, so as to sharply reduce the internal friction between soil particles and achieve the purpose of compacting soil; The magnitude of the exciting force can be adjusted as needed. The difference is that the towed roller cannot walk. It can walk and compact only when dragged by other tractors. According to different compaction thickness and materials, different rolling wheel mass or static or vibration can be selected.
超重吨位拖式振动压路机是高速公路、铁路、水坝、机场等大型工程基础施工中不可缺少的压实机械，特别是对于大填方施工，当压实度要求95%以上时，更显示出这种机械的必要性。多年来，国内外生产的拖式振动压路机几乎全为机械传动方式，这种方式的特点是成本低、传动效率高，然而在实践中也暴露出许多缺点，如可靠性、传动效率并不如理想的那样高，机架不能有效隔振影响压实效果等。因此，在当前国加大基础设施建设力度的大前提下，工作可靠、性能优良的液压传动拖式振动压路机的发展就成为必然。
Super heavy tonnage towed vibratory roller is an indispensable compaction machine in the foundation construction of large-scale projects such as expressway, railway, dam and airport. Especially for the construction of large fill, when the compactness is required to be more than 95%, it shows the necessity of this kind of machine. Over the years, the towed vibratory rollers produced at home and abroad are almost all mechanical transmission mode. This mode is characterized by low cost and high transmission efficiency. However, many shortcomings have been exposed in practice, such as reliability and transmission efficiency are not as high as ideal, the frame can not effectively isolate vibration and affect the compaction effect, etc. Therefore, under the premise of strengthening infrastructure construction, the development of hydraulic driven towed vibratory roller with reliable work and excellent performance has become inevitable.
