    • A method of developing a can (e.g. beverage) bottom profile is presented. More specifically, finite element analysis on a parametric representation of a beverage can is used for developing an improved beverage can design. By specifying performance parameters that the beverage can must meet and providing specific geometric limitations on the design an improved beverage can design is obtained. The resulting improved beverage can design is independent of the gauge of the material used in construction thereof. The improved beverage can provides a concave dome on the bottom of the can connected to a bottom stand which in turn is connected to a cylindrical side wall of the can via a slanted connecting wall.
    • 提出了一种开发罐(例如饮料)底部轮廓的方法。 更具体地说,使用饮料罐参数表示的有限元分析来开发改进的饮料罐设计。 通过指定饮料必须满足的性能参数并在设计上提供具体的几何限制,可以获得改进的饮料罐设计。 所得到的改进的饮料罐设计与其在构造中使用的材料的规格无关。 改进的饮料可以在连接到底架上的罐的底部上提供凹入的圆顶,底座又通过倾斜的连接壁连接到罐的圆柱形侧壁。
