Intensity Finite-Element-Analysis of a Packing Box According to the Hull Unit

包装箱承受产品重力、气压和过载等载荷。使用hypermesh软件对箱体进行了四边形壳单元建模，并对箱体结构进行了强度计算分析，得出了箱体的应力和变形云图，对设计中的薄弱环节进行了改进，并对改进后的包装箱强度进行了计算和验证。 The packing box bears product gravity, air pressure and overload. The box is divided by quadrila-teral sheel element grid with hypermesh software, and intensity finite-element-analysis of the box is carried on. Stress and deformation cloud of the box is calculated. Then the weakness of the box is analyzed and improved. And the intensity of the improved box is also calculated and validated.
