摘　　要：运用Unigraphics软件和有限元分析软件Abaqus对某型冰箱搁物架承重横梁四种不同的设计方案进行了强度和变形对比分析,并选择出了最优设计方案。与传统方法相比,这种做法的优点是:在产品设计阶段采用有限元理论分析对产品的使用性能进行仿真,可以方便观测设计更改对产品性能的影响,选择最优设计。这样不仅能够保证设计产品的质量,而且大大加速产品开发过程,提高设计一次成功率。The optimization design of a supporting bar in a refrigerator is realized based on the FEM analysis.Firstly,four possible design models for a supporting bar are established using the CAD software Unigraphics.Then,the finite element analysis is performed on those design models by applying the software Abaqus.The distribution of the displacement and stress field is obtained.Finally,the maximum displacement and stress are compared and an optimal design is selected.Compared with the traditional product design process,this new method not only can guarantee the quality of the designed product,but also can largely shorten the development cycle and improve the design reliability.
