摘　　要：为验证离散元法分析犁体耕作阻力的可靠性,利用离散元仿真对犁体阻力进行分析。通过多组参数的仿真试验,获得在不同含水率土壤条件下进行不同耕深的犁体牵引阻力数据。结果表明,犁体的土壤耕作阻力随着土壤含水率与耕深的增大而增大,与田间耕作结果一致,证明了离散元法分析犁体土壤耕作阻力的可行性,为犁铧的耕作模拟仿真研究提供一定参考。In order to verify the reliability of the discrete element method to analyse the plough body ploughing resistance,the plough body resistance was analysed by using discrete element simulation.The data of plough body traction resistance for different ploughing depths under different water content soil conditions were obtained through simulation tests with multiple sets of parameters.The results show that the soil tillage resistance of the plough body increases with the increase of soil water content and ploughing depth,which is consistent with the results of field ploughing,proving the feasibility of the discrete element method to analyse the soil tillage resistance of the plough body,and providing a certain reference for the research of ploughing simulation of ploughshare.
