新型可变容积纸容器的折叠尺寸参数研究

Research on Folding Size Parameters of a New Volume Changeable Paper Container

以正方形截面为例,推导了新型可变容积纸容器各尺寸参数间的关系,建立了不同截面情况下的尺寸关系模型。结果表明:当截面形状不变且为正多边形时,各尺寸参数只与折痕宽度有关;随着折痕宽度的增大,所有参数都按比例同步增大,即该类新型纸容器的各折边长度尺寸由截面形状及折痕宽度唯一确定。

The relation among folding size parameters of new volume changeable paper container were deducted with examples of square cross-section paper containers. The size relation model was established under different section. The results showed that when the cross-sectional shape as a regular polygon unchanged, all the param- eters are only associated with the width of the crease. They were changed by the same proportion as the width of crease increased. That is, such new paper containers＂ parameters are uniquely determined by the cross-sectional shapes and the width of crease.
