为了进一步验证数值模拟的可行性，利用ANSYS进行土壤耕作过程的模拟研究，得到变形区应力分布，并研究耕作阻力的变化。试验与模拟结果均表明，靠近犁体曲率最大处的土壤变形区，在犁体前进方向上的应力最大；在耕作过程中，耕作阻力先逐渐增大，然后略有减小，最后稳定在某值基本不变。

In order to verify the feasibility of data simulation , the tillage experiment was carried out and the stress in the advancing direction of plough was measured .Based on ANSYS , soil tillage process was simulated , and the over-all distribution of stress within deformation zone was studied as well as the changes of tillage resistance .It was shown that the highest stress toward the heading direction occurred in the soil deformation zone of the maximum curvature of plough .During the tillage process , the tillage resistance increased first and then reduced slightly , and finally reached stable.
