摘要
本研究通过磨损前后犁铧刃口受力分析，探讨在耕作过程中铧刃阻力与土壤比阻、土壤—金属摩擦系数、铧面角、推土角及磨损后刃口的背棱宽度、负隙角。
By means of effort analysis of new and worn plowshare blades, the relations between resistances of the plowshare blade and the soil resistance of per area,a friction factor of soil and metal,a angle of plowshare surface,a angle of pushing soil and the land width,a negative clearance and a corner radius of worn plowshare blade are studied in this paper.
