| 目的 研究影响 2片罐轴向承压能力和耐压强度的因素。 方法 通过有限元屈曲分析方法，首先分析相关部位的厚度变化对以上 2指标的影响， 分析总结 2片罐拱底半径、拱底高度以及侧壁的高度与这2项指标之间的关系。 结果 圆柱部位侧壁厚度越大， 轴向承压能力越强； 罐底厚度对轴向承压能力在理论上没有影响， 但耐压强度会随着罐底厚度的增大而增强；拱底直径的增大在一定范围内会使轴向承压能力增大， 但超过这个范围这个影响就没有了 ， 而耐压强度在保持拱底高度不变的前提下会随着拱底直径增大而减小； 拱底高度越大， 两片罐的耐压强度越强， 但是拱底高度对轴向承压能力没有影响；圆柱部位侧壁高度变化对轴向承压能力和耐压强度都没有影响。 结论 材料厚度和结构均对轴向承压能力和耐压强度有一定的影响，可以通过结构的优化达到轻量化设计的目的。 |

| Objective To study the influencing factors for the axial bearing capacity and the compressive strength of two-piece can. Methods Through the method of finite element buckling analysis, the influence of the thickness of relevant part on the above two properties was analyzed firstly and the relationship between the two properties and base radius, base height and cylinder height of the two-piece can was also analyzed. Results The thicker the cylinder wall, the stronger the axial bearing capacity. Base thickness did not influence the axial bearing capacity in theory, but the compressive strength became stronger with the increasing base thickness. Axial bearing capacity increased with the increasing base diameter within a certain range, but was not influenced beyond that range, the compressive strength became smaller with the increasing base diameter when the base height was unchanged. Compressive strength became stronger with the increasing base height, but the base height did not influence the axial bearing capacity. The height of cylinder wall did not influence both the axial bearing capacity and the compressive strength. Conclusion Material thickness and structure both influenced the axial bearing capacity and the compressive strength, light-weight design could be realized through the optimization of structure. |
