Vibrating plate compactors are mainly suitable for materials with less cohesion and friction between compacting particles, such as river sand, gravel and asphalt. The main working parameters of the vibrating plate compaction are: the bottom area of the working plate, the mass of the whole machine, the excitation force and the excitation frequency. Under normal circumstances, the bottom plate area of the same type of plate is about the same, so the performance of the plate rammer is mainly affected by the quality, excitation force and excitation frequency of the whole machine. The excitation force is mainly used to maintain the forced vibration of the tamped material; The excitation frequency affects the tamping efficiency and compaction degree, that is, under the same excitation force, the higher the excitation frequency, the higher the tamping efficiency and compactness.
