Transport of heap formed by granular materials on an inclined surface

We study experimentally the transport of heap formed by granular materials vertically vibrated on an inclined surface. A relationship is presented of how the velocity of heap changing with driving acceleration and frequency. The shape of the heap bottom is measured by detecting the colliding phase of the heap bottom with plane. An analogous experiment is performed with a heap shape block of Plexiglas. The mechanism for transport of the heap is presented.
