The working principle of small road rollers is mainly based on the combination of static pressure and vibration force. Static pressure is generated by the weight of the roller itself. When the roller travels on the ground, its weight will generate a certain pressure on the ground, so that the gaps between the soil or material particles are compressed, thus achieving the effect of compaction. The vibration force is generated by the vibration device on the roller, which is usually composed of a vibration motor, an eccentric block and a vibration shaft. When the vibration motor is started, the eccentric block will generate centrifugal force to drive the vibration shaft to rotate, thus generating high-frequency vibration. This vibration can rearrange soil or material particles to further improve compaction.
In the working process of small road roller, static pressure and vibration force interact and complement each other. Static pressure can form a preliminary dense structure between soil or material particles, while vibration force can further eliminate the voids between particles and improve the compactness. At the same time, vibration can also reduce the friction between soil or material particles, reduce compaction resistance and improve compaction efficiency.
