目的 以板材包装结构为研究对象，研究其承载能力。方法 运用力学原理对结构强度进行定性分析，同时利用有限元软件Ansys Workbench进行定量分析。结果 得到了承载不同厚度铝板的包装结构正应力云图及最多能承载铝板的数量。结论 板材厚度对结构的力学模型有较大影响。承载厚板时结构危险截面剪应力较大，剪应力成为控制条件；承载薄板时结构危险截面正应力较大，正应力成为控制条件。

The work aims to study the bearing capacity of plate packaging structure with such structure as the study object. The qualitative analysis and quantitative analysis of its structural strength was done by using mechanics principle and Ansys Workbench separately. The normal stress nephogram of packaging structure bearing aluminum plates of different thicknesses, together with the corresponding number of aluminum plates were obtained. In conclusion, plate thickness has great influence on the mechanical model of the structure. The shear stress of the dangerous section is larger when the structure is bearing thicker plates, and the shear stress will be the controlling condition; while the normal stress of the dangerous section is larger when the structure is bearing thinner plates, and the normal stress will be the controlling condition.
