- Abstract:
-
Aiming at the insufficient compaction performance of the current single-frequency vibration compaction machinery, a dual-frequency vibration compaction machine based on dual-frequency synthesis technology is proposed, and the dynamic model of the machine is established. After experimental research, it is concluded that dual-frequency vibration compaction is better than single-frequency vibration compaction, and that the phase angle selection at (-300,300) has a better effect on deep compaction, and the two-excitation frequency ratio is selected as 3:2, that is, the high frequency is 33.98 Hz and the low frequency is 22.44Hz, the compaction effect is better. And when designing a dual-frequency vibrating roller, the frequency, amplitude, phase angle and other important parameters affecting compaction are given a reasonable choice.
