%X The vibration friction mechanism of granular material in vibration case was revealed. A curve of vibration parameters to internal friction of soil was given. With numerical experiments, the complicated process of vibration friction compaction was simulated. Curves of frequency and amplitude to void ratio and mean stress were given, which verified the mechanism of vibration friction. The results indicated that static friction converted to dynamic friction in vibration case; both internal and external frictions decreased with increasing frequency and amplitude. An optimal vibration intensity can lead to the lowest internal friction. Finally, a nonlinear dynamic model of vibration friction system with compaction equipment was proposed. Its resonance and non-resonance responses were obtained.
