摘　　要：本文通过对市售陇薯3号、新大坪和庄薯3号3种马铃薯尺寸进行统计,并获取了典型马铃薯几何尺寸的统计值,挑选尺寸与统计值最相近的马铃薯对其进行切片,利用切片造型技术在Solidworks软件生成马铃薯实体模型,应用ANSYS软件对马铃薯X、Y、Z三个方向加载时的应力变形情况进行分析。分析结果为:X向加载时最大应力为1.27Mpa,最大位移为9mm;Y向加载时最大应力为5.84Mpa,最大位移为9.3mm;Z向加载时最大应力为3.94Mpa,最大位移为28mm。Based on market sales longshu 3, New Daping and Zhuangshu 3 3 kinds of potato size statistics, and the statistics of typical potato size value was acquired. Potato contour data were obtained with Slice shaping technology and potato model was generated with Solidworks. The stress and deformation of potato model while loading in X, Y, Z three directions were analyzed. Results as： In X loading the maximum stress was 1.27Mpa and the maximum displacement is 9ram; In Y loading the maximum stress was 5.84Mpa and the maximum displacement is 9.3mm; In Z loading the maximum stress was 3.94Mpa and the maximum displacement is 2.8mm.
