马铃薯仿生挖掘铲减阻性能研究
Research on the drag reduction performance of potato bionic digging shovel
摘要
Abstract
According to the stereoscopic microscopic photograph of first toe of claw toe in forefoot of the mole cricket has designed the shovel of the excavator and carried out the research for the drag reduction and pulverized soil performance,based on the discrete element method carried out the numerical simulation process for the bionic shovel excavated soil.In order to protrude the good excavating performance of the bionic shovel,under the same condition compared with the ordinary shovel carried out the comparison of the simulation results.The results showed that: As compared with the ordinary shovel,the forward resistance of the bionic shovel was reduced 11.36％and the vertical direction was reduced 17.65％.Comparing the number of soil particle adhesion between two kinds of shovel excavated soil,we can know the soil crushing rate of the bionic shovel was higher than ordinary shovel by 2.68％.The bionic excavating shovel can shear and break the uplift soil and gradually reduce the horizontal and ver-tical resistance,so it has a good application prospect.关键词
