摘　　要：深松铲是保护性耕作深松机的重要关键部件,其作业时的减阻降耗问题近年来成为热点。针对这一问题,提出仿生减阻设计方法,在深松铲触土截面上拟合穿山甲挖穴爪趾的曲线,并在有限元计算软件中验证其合理性,最后通过实际田间试验对比证明该设计方法可以有效实现深松机的减阻降耗。Shovel is the key component for protecting the tillage subsoiler,and its drag reduction and saving has become a hot topic in recent years.To solve this problem,the design method of biomimetic drag reducing was proposed,and the curve fitting of pangolin digging claw toe on the soil-touch section of shovel was conducted.Its validity was verified in the finite element software.Comparing in the actual field experiments,this method can effectively achieve shovel＇s drag reducing with a wide range engineering applications.
