摘　　要：采用Solid Works软件对4SW-170型马铃薯收获机摆动筛进行三维建模,通过理论分析摆动筛在工作时物料在其上的运动状态,采用计算机分析软件Mat Lab对摆动筛上物料的运动进行数值模拟,并通过与理论分析相比较,验证了数值模拟的可靠性。针对摆动筛及薯土物料的运动特殊性,特使用高速摄像技术对摆动筛在工作过程中筛上马铃薯的运动特性进行分析,为进一步观察马铃薯在筛面上的运动情况、研究物料的不规则运动、合理选择运动参数及提高筛分效率提供依据。This paper uses the software of Solidworks for potato harvester the type of 4SW-170 vibrating screen for 3D-modeling , through the theoretical analysis of vibrating screen material at work on its state of motion , and uses the com-puter analysis software MATLAB numerical simulation was made for material movement on the vibrating screen .Through comparing with the theoretical analysis , the reliability of the numerical simulation is verified .For the speciality of vibra-ting screen and potato soil materials movement , using with the high-speed camera technology of vibrating screen oversize potatoes in the working process of the movement characteristics analysis , In order to observing further movement situa-tion, researching the material on the surface of the potatoes in the screen irregular movement and choice the parameters reasonable , it also provides the basis for improve the screening efficiency .
