振動壓路機是利用其自身的重力和振動壓實各種建築和築路材料。適宜壓實各種非粘性土壤、碎石、碎石混合料以及各種瀝青混凝土。在振動壓路機作業過程中，由於振動壓實的需要，經常需要調節振動輪振幅。下麵小編就帶大家一起來了解一下振動壓路機的工作原理。
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.
當振動壓路機激振器固定偏心塊與振動軸固接在一起，另一動偏心塊空套在振動軸上。當振動馬達正反轉時，則產生了兩種不同的偏心塊疊加方式，能得到兩種不同的靜偏心矩。激振器振動調幅機構振動軸順時針旋轉時，動偏心塊與固定偏心塊靜。偏心距相加，從而產生大振幅；振動軸逆時針旋轉時， 動偏心塊與固定偏心塊靜偏心距相減，從而產生小振幅。
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.
與自行式振動壓路機的工作原理相同，拖式振動壓路機也是依靠自重和激振力迫使被壓實材料做垂直強迫振動，急劇減小土壤顆粒間的內摩擦力，達到壓實土壤的目的；激振力的大小可以根據需要進行調整。不同的是拖式壓路機不能行走，通過其他牽引車拖動才能行走和壓實。根據不同的壓實厚度和材料可選擇不同的碾壓輪質量或靜力或振動。
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.
超重噸位拖式振動壓路機是高速公路、鐵路、水壩、機場等大型工程基礎施工中不可缺少的壓實機械，特別是對於大填方施工，當壓實度要求95%以上時，更顯示出這種機械的必要性。多年來，國內外生產的拖式振動壓路機幾乎全為機械傳動方式，這種方式的特點是成本低、傳動效率高，然而在實踐中也暴露出許多缺點，如可靠性、傳動效率並不如理想的那樣高，機架不能有效隔振影響壓實效果等。因此，在當前國加大基礎設施建設力度的大前提下，工作可靠、性能優良的液壓傳動拖式振動壓路機的發展就成為必然。
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.
