摘要
针对当前单频振动压实机械的压实性能不足现象,提出了一种基于双频合成技术的双频振动压实机械,建立了该机械的动力学的模型。经过试验研究,得出双频振动压实优于单频振动压实,以及相位角选择在(-300,300)对深层压实效果较好,两激振频率比选择为3:2,即高频为33.98 Hz,低频为22.44 Hz时,压实效果较好的结论。并给出了在设计双频振动压路机时,频率、振幅、相位角等影响压实重要参数的合理选择。
In view of the phenomena of insufficient compaction about the single - frequency vibration compaction, the paper puts forward the double - frequency vibration compaction based on double - frequency vibration superposition, and builds the dynamic model. The experimentation result indicates that the double-frequency vibration compaction is better than the single - frequency one , and it can also be known that the phase angle selected at（ - 30°, 30°） is preferable for compaction on deep soil , and the compaction effect is better when the ratio of the two vibration frequencies are selected at 3：2,that the high frequency is at 33.98Hz, and the low one is at 22.44Hz. Some suitable parameter values affecting the soil compaction are given in the design of the double - frequency vibration compaction, such as ratio of vibration, ratio of amplitude and phase angle etal.
