Mechanism of Friction and Wear of Steel Plate Against Solidified Sandy Soil

Abstract

In this paper the mechanism of the frictional resistance and the wear of steelplate for solidified sandy soil are cleared and shown. The solidified sandy soil was used to make reappear the heaviest wear in actual earth moving operation. It resulted that the frictional resistance increases linearly with increasing of contact pressure, and the relation between the contact pressure and the amount of wear of metal can be calculated from the depth of penetration of soil particle into metal plate. And the amount of wear of metal increases in proportion to about 0.84～1.00 power of the contact pressure.
