【摘要】 以浙江永成集团ZJ013860型离心铸造机为研究对象,对其现有结构基于ANSYS Workbench进行有限元分析,就弯曲应力及弯曲变形挠度两方面对离心铸造机主轴进行结构优化,优化后相比原铸型最大变形值降低了81%;主轴变形值降低了73%;主轴危险截面应力值降低了70%,并对优化后结构进行模态分析,校核了临界转速。更多还原

【Abstract】 With ZJ013860 centrifugal casting machine of Zhejiang Yongcheng Group as the research object,this paper conducts finite element analysis on its existing structure based on ANSYS Workbench and optimizes the structure of main shaft of centrifugal casting machine in terms of bending stress and bending deflection.After optimization,compared to the original casting mold,the maximum deformation value,main shaft deformation value and dangerous section stress value of main shaft respectively decrease by 81%,73% and 70%.This paper conducts modal analysis on the optimized structure and verifies critical speed of rotation.更多还原
