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22.44Hz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.

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.
