土壤对机械和机具的粘附是一个亟待解决的重要问题。本研究根据典型土壤动物蜣螂头部非光滑表面形貌设计了非光滑推土板。这种非光滑推土板的推土阻力随着推土板表面贴敷的小凸包的分布、凸包材料、切削速度、切削角、切削深度及土壤含水量的不同而变化。含水量由30.38％增加到35.50％,推土阻力随之减小。精选推土板之平均最大降阻可达30％。研究结果还表明超高分子量聚乙烯(UHMW—PF)能够明显地减粘降阻。 Soil adhesion to machinery and equipment is an important issue to be solved. In this study, a non-smooth earthwork was designed based on the non-smooth topography of the typical soil animal dung beetle. The drag resistance of this non-slip earth-moving plate varies with the distribution of the small convex hull applied to the surface of the earth slab, the material of the convex hull, the cutting speed, the cutting angle, the cutting depth and the soil water content. Water content increased from 30.38% to 35.50%, the resistance of the soil decreases. Select the best average drag reduction board up to 30%. The results also show that ultrahigh molecular weight polyethylene (UHMW-PF) can significantly reduce viscosity reduction.
