Plate vibratory compactor is the same with building site roadbed and road shoulder road maintain n pitch road surface remedy and tamp of channel and trench, either auto timing tread or original tamp, manipulate simpleness and freely, work efficiency high. dynamic properties of the plate vibratory compactor are studied, and the compaction process is theoretically discussed in this paper
平板振動夯適用於建築工地、路基路肩、道路維修、瀝青路面修補及溝渠的夯實平整，既可自動調速行走，也可原地夯實，操作簡單自如，工作效率高。為了探索平板振動夯在壓實過程中的動力學特性，以便為平板振動夯的研製提供理論基礎。 -
The experimental model is a rectangular section of 15. 2 187mm ~ 2, which is composed of two aluminum plates. the angles between the internal netted rib turbulators and the flow direction are 45 ? for the one plate and 60 ? for the other, or both 45 ? for two plates. in the experiment, the re numbers changes from 0. 4 10 ~ 4 1. 5 10 ~ 5, rib width - to - pitch are 0. 25, 0. 3 and 0. 5, rib width - to - height are 0. 25, 0. 3 and 0. 5, the rib height - to - hydraulic diameter ratio is 0. 246
