The technique of paralleling motivation with impact and vibration for impact roller

In this paper a new kind of compaction device and system is introduced for the impact roller. It could generate strongly impact fore and high frequency vibration to soil at the same time but no additional force to roller oneself. A series of problem has been solved that proceed from the present impact roller. The principle and action mode has been introduced, which can create multiple impact and vibration motivation. Reasonable structure parameter has been chose by dynamic optimization design. The impact energy can be switch over compression energy of soil at the full. The research has also analyzed the resistance fluctuation condition and the variety rule of the traction peak when working wheel rolling by 3-d simulation technique, and the life of machine is estimated. The stable load characteristic can lead the drawbar power of impact roller to reduce 25%, and the life of mechanical part can increase by 100%. It is a valid method of compaction construction with high-efficiency, high- quality and lower energy.
