摘    要:对模拟土壤动物典型几何非光滑表面的各种形状的仿生非光滑推土板在固,液,气三相组成的土壤中,进行了减粘降阻试验研究,试验土壤为砂土,湿砂土,松散黄粘土和结构性较好的黄粘土,研究非光滑表面改变切削深度,切削角度探讨了下减粘降阻效果及非光滑表面减粘降阻机理,结果表明,在切削成垡状粘性土壤时,非光滑表面可降低阻力25%以上,且其脱土性能比光滑板好。

关 键 词:非光滑表面  土壤  仿生  推土板

Abstract:In this paper, reducing adhesion and resistance experiments for various bionic nonsmooth bulldozing plate imitating the nonsmooth surface of typical animals were made in soil, such as sand, wet sand, loose sticky soil and sticky soil with certain soliding. The results and mechanism of reducing adhesion and resistance by nonsmooth surface under changing cut depth and angle were analyzed. The results showed that the function reducing adhesion and resistance of nonsmooth surface was poor for sand and loose soil. Nonsmooth surface can reduce adhesion, but its resistance reduced less for the disturbed loose yellow clay with moisture content between plastic limit and liquid limit. Only when the soil was cut to form upturned soil and move along the surface of soil touching parts in belt shape, the nonsmooth surfaces have good function reducing adhesion and resistance. Nonsmooth surface can produce 25% reduction of resistance and scour soil more than smooth surface. In spring or autumn ploughing soil is almost turn up in this shape at adhesive field. So the study on nonsmooth surface has more practical significance.
Keywords:Nonsmooth surface  Soil  Bionic  Bulldozing plates
