1. Compaction depth: A higher vibration frequency can usually achieve more efficient compaction at a shallow depth, which is suitable for compacting thinner layered materials; a lower vibration frequency can transfer more energy to deeper soil layers, and has a better compaction effect on deep soil.
2. Compaction efficiency: A higher vibration frequency can provide more vibration times per unit time, thereby speeding up the progress of compaction operations and improving work efficiency.
3. Material adaptability: For materials with larger particles and higher hardness, a lower vibration frequency may be more conducive to transferring vibration energy to the inside of the particles and achieving better compaction; while for fine particles and soft materials, a higher vibration frequency can make the material denser more quickly.
4. Surface flatness: Too high a vibration frequency may cause excessive vibration of the surface, affecting the flatness; an appropriate vibration frequency helps to maintain a good surface flatness while ensuring the compaction effect.
5. Prevent over-compaction: For certain specific materials, if the vibration frequency is too high, it may cause the material structure to be damaged, resulting in over-compaction, which in turn reduces the bearing capacity and stability of the base layer.
