摘　　要：对4U-1400FD型马铃薯联合收获机的挖掘铲建立牵引阻力的数学模型,在此模型下分析挖掘铲的铲面倾角、作业速度、挖掘深度、铲体长度等因素对挖掘铲牵引阻力的影响.结果表明:挖掘铲参数的最佳组合为铲面倾角20°,铲体长度470mm,铲宽1 400mm.通过田间试验,该挖掘铲的性能符合规定的指标.The mathematical model on traction resistance of digging blade of the 4U-1400FD potato combine harvester was established.Based on this model,the influences of the obliquity of blade,working velocity,digging depth and blade length on traction resistance were analyzed respectively.The optimum parameters combination for the digging blade was as follows：obliquity of blade was 20°,blade length was 470 mm,digging breadth was 1 400 mm.Through the field experiment,the function of this combination digging blade coincided with prescriptive index sign,and thereby laid the foundation for the further optimal design of the whole machine.
