摘要
为了解决烟草物流配送包装机风机叶轮轴使用寿命低的问题,文章以风机叶轮轴为研究对象,利用Solidworks软件建立3D模型,再利用Abaqus有限元分析方法对其进行热力顺序耦合分析,根据风机叶轮轴的温度场分布、受力和变形情况,对轴的结构进行优化设计,并对轴进行模态分析,确定风机轴的临界转速,结果表明,风机轴的优化设计合理,满足生产要求。
In order to solve the low service life of the fan impeller shaft in tobacco logistics packaging machine,the fan impeller shaft was taken as the research object,Solidworks software was used to build a 3D model and the Abaqus finite element analysis software was used to perform the analysis of thermal-mechanical coupling.According to the distribution of temperature,stress and deformation field of the fan impeller shaft,for the shaft structure optimization design and the modal analysis were carried out to determine the critical speed of the fan.The results show that the optimization design of shaft is reasonable,meeting the requirements of production.
