Analysis of the bubble performance of the aluminum tube during processing, which includes a telescopic rod body, which includes a number of aluminum tubes. The aluminum tubes are connected through plastic guide sleeves. The aluminum tube is constructed of an eccentric rod, and the bottom of the aluminum tube is provided with plastic slip sheets; The inner upper part of the aluminum tube is provided with a boss, and the bottom of the boss is provided with a chamfer; The sides of the plastic guide sleeve are averagely provided with through holes, and the middle part of the side of the plastic guide pipe is provided with a stage.

The plastic guide sleeve is clamped on the chamfer at the bottom of the inner boss of the aluminum tube through the step on its side, and is pressed into the aluminum tube; It has the advantages of simple structure and easy operation. The deformation mechanism of aluminum foam during compression is collapse layer by layer; When aluminum foam is stretched, its elastic modulus is proportional to the square of the relative density, and its tensile strength is proportional to the relative density.

The longitudinal and transverse compression tests of aluminum foam filled tubes were carried out. The results show that the deformation forms of aluminum foam filled tube and aluminum tube are the same, both of them are symmetrical and superposed, but the folding of the filled tube is more than that of the empty aluminum tube.

的阶台卡扣在铝管内凸台底部的倒角上，压入铝管内；它具有构造简单，操作便当，泡沫铝紧缩时变形机理为逐层坍塌；泡沫铝拉伸时弹性模量与相对密度的平方成正比，抗拉强度与相对密度成正比。

    对泡沫铝填充管做了纵向紧缩和横向紧缩实验。结果标明：纵向紧缩时，泡沫铝填充管和铝管的变形形式相同，都是对称叠缩变形形式，但是填充管产生的折叠比空铝管多。
