Abstract
Unsmoothed bulldozing plates were designed and tested by imitating the surface morphology of the top of the head of the dung beetle (Ohthoph agus lenzii harold) on the D-optimum theory. The results showed that t he bulldozing resistance of the unsmoothed plates was, on average, red uced by 13.02% and that of the optimum plate was reduced by 18.09% in comparison with a conventional (that is, smooth) plate. The mechanism of reducing sliding resistance of the unsmoothed surfaces was discusse d. Copyright 1996 Published by Elsevier Science Ltd.
