基于ANSYS Workbench的液压支架推移杆有限元分析

摘要

通过在SolidWorks中对液压支架推移杆进行三维实体建模和在ANSYS Workbench中的有限元分析，不仅得到了井下3种常见工况下推移杆上最大应力和最大变形量以及其存在的危险部位，还找到了推移机构初步设计的结构缺陷，结果证明在机械零部件设计中应力集中不可忽略。%A three-dimensional model was set up for the push bar of a hydraulic support using SolidWorks ,and the finite element analysis and research on the push bar was carried out by ANSYS Workbench .The stress and displacement distribution of the push bar in three common conditions were obtained ,and the structure defects of the push bar in the preliminary design were found out . The results show that the stress concentration cannot be ignored in mechanical part design .
