　　深松技术是旱地保护性耕作体系中的重要技术措施之一，高效节能是深松技术的发展方向。深松铲所受阻力是深松耕作的主要阻力来源。通过对金龟子和家鼠的足趾结构的研究，设计了一种新型的深松铲结构。结合四川的土壤条件，采用Drucker-Prager 模型，利用有限元分析软件Abaqus 对深松工艺数值仿真。在20℃常温和23°切削角的条件下，与JB/T 9788-1999深松铲比较，新型深松铲土壤应力分布和土壤扰动轮廓一致，深松铲所受土壤的反作用力减小，在相同前进速度和耕作深度的情况下，功率消耗降低了20．6％。

Subsoiling is an important technique of conservation tillage systems on dry land .High efficiency and energy saving are required in subsoiling techniques .A new subsoiler structure is presented by study on toes ’ structures of scarab and rats .Consider the soil conditions in Sichuan , a subsoiling process simulation using drucker -prager model is per-formed by finite element analysis software of Abaqus , comparing new subsoiler with JB/T 9788-1999 subsoiler under the condition of 20℃room temperature and 23 °cutting angle , simulations ’ results show that soil stress distributions are i-dentical with soil disturbance contours , and the reaction force from the soil decreased , power consumption was reduced by 20 .6%with the same speed and depth .
