摘　　要：通过对马铃薯的静剪切应力的试验,获得了不同品种、不同含水率及在载物架上的马铃薯不同位姿时的马铃薯最大静剪切力。采用黑龙江省常见的克新13品种和尤金885品种为研究对象,利用微机控制电子万能材料试验机进行马铃薯静剪切力的试验。试验结果表明:在一定含水率范围内,随着含水率的降低其最大静剪切力会增加;马铃薯在载物架上的位姿对最大静剪切力也有影响,位姿不同所需的剪切力也会不同。By the test of static shear stress,obtaining different potato varieties,different moisture content and the cargo on the shelf when different pose the biggest potato static shear force,the main varieties in Heilongjiang province are Kexin13 and Youjin 885 as the research object,the use of microcomputer control electronic universal material testing machine for potato static shear test.The results show that the maximum static shear force increases with the decrease of water content within a certain range.The posture of the potato on the loading rack also has an influence on the maximum static shear force.The shear force required for different posture will also be different,which is mainly related to the micro cells inside the potato.
