| Research Abstract |
The purpose of the present research is to develop a new mechanism for a tamping rammer using self-synchronization phenomena in order to address the problem of the hand-arm vibration syndrome. It was proven that suitable synchronous vibration could be generated in the elementary model, and that the existence region of these synchronized solutions can be expanded by setting the system parameters appropriately. In addition, the prototype has been developed based on the mechanism of the impact model with four oscillators. After conducting the sand compaction test, it was confirmed that the suitable synchronized vibration can be generated continually.
