Research On Vibration Compaction Frequency Based On Vibrational Signal From The Ground Surface

The vibration roller is an important device in a road construction. Its major technical parameters have not only impact on compaction effect but also compaction efficiency. This paper has mainly studied the influencing factor of vibratory roller's frequency to compaction effect,and put forward a novel method for controlling vibratory roller's compaction frequency,and made pilot study of sand compaction frequency.The vibration compaction mechanism and compaction theory were studied in this paper. After analyzing the classical technical parameters-vibration frequency and amplitude, the novel method and the realization way which could control vibratory roller's compaction frequency based on ground vibrational sinnal were proposed;By researching ground vibrational signal with vibration energy ,a feasibility study on controlling vibratory roller's compacted optimum frequency was analyzed;The contrast experimentation result indicates that the optimum frequency vibration compaction is better than the general one. This paper presented a new idea of research on vibratory roller's compacted frequency,and provide the basis for technology of stepless adjustment on vibration frequency. It has use value for designing vibration road roller.
