摘　　要：压榨螺旋是螺旋压榨机工作装置的基础部件和关键部件之一,其强度是影响压榨性能关键因素。为此,根据压榨螺旋的工作特点及其材料属性的要求,对压榨螺旋进行了理论受力分析,并在此基础上对其进行了有限元分析,最终确定了整个压榨螺旋的受力分布情况;最后,在对螺旋ANSYS的后处理结果进行了理论分析,确定在正常的工况下螺旋强度是完全满足工作要求的。本研究可为螺旋压榨机对农业物料进行正常的压榨分离提供保障。The screw press is mainly composed of power plant,extrusion screw,spiral pipe,press ontology,feed hopper and hopper,etc,and press screw is the basic unit of such screw press working device,and it is the one of the key parts working process.Its strength can meet the requirements of the performance and its squeezing effect is the key factor.Therefore,according to the press screw working characteristics and the material properties,at the request of press screw theory force analysis,based on the finite element analysis,we have determined the whole press screw stress distribution.Finally,based on the helical ANSYS post-processing results and the basis of theoretical analysis,we can determine the screw working in the normal condition.Its strength is completely meeting the job requirements.This research for agriculture in screw press for agricultural materials are normal press separation to provide security.
