The vibratory drum is the component of a vibratory roller that directly contacts the ground. It applies static weight and dynamic vibration to compact soil, gravel, or asphalt, increasing density and stability.
Higher frequencies (e.g., 45 Hz) are typically used for asphalt to achieve smooth finishes, while lower frequencies (e.g., 30 Hz) are used for soil to achieve deeper compaction. The optimal frequency depends on the material and layer thickness.
Centrifugal force, generated by the rotating eccentric shaft, determines the compaction energy and depth. Higher forces (up to 400 kN) are suitable for thick layers, while lower forces are used for thin layers to avoid over-compaction.
Vibration isolation reduces the transmission of vibration from the drum to the roller frame and operator, improving comfort and reducing wear on machine components. Typical isolation efficiency is 85–95%.
