摘　　要：为确保便携式微波真空烘箱的谐振腔满足轻量化设计的同时,兼顾结构强度的需求,对烘箱谐振腔体的强度进行了有限元分析。采用三维设计软件SoildWorks建立了谐振腔结构三维模型;通过合理简化结构组件,并在有限元软件Abaqus中完成网格划分以及边界条件设置,建立了烘箱的有限元模型;通过Abaqus软件对模型进行了静态分析和模态分析。有限元分析结果符合理论化设计要求,且结果表明,此便携式微波真空烘箱在实际使用过程中不存在塑性形变和结构共振的问题,满足产品使用需求。In order to ensure that the resonant cavity of the portable microwave vacuum drying oven meets the lightweight design while taking into account the needs of structural strength,the finite element analysis of the strength of the resonant cavity was carried out.The three-dimensional model of the resonant cavity structure was established by using the 3D design software SoildWorks.The finite element model of the drying oven was established by reasonably simplifying the structural components,completing the meshing and setting the boundary conditions in the finite element software Abaqus.The static analysis and modal analysis of the model were carried out by Abaqus software.The finite element analysis results meet the theoretical design requirements,and the results show that this portable microwave vacuum drying oven does not have plastic deformation and structural resonance problems in the actual use of the product to meet the use of demand.
