Abstract

Abstract: In order to research the dynamic damping performance of square steel tube filled with foam aluminum,the damping properties of empty square tube,two forms of foam aluminum filling square tube (with glue and without glue)are studied by using experiment and simulation method,respectively.And the mechanism of damping is also analyzed.The results show that the foam aluminum filling can significantly improve the damping performance of empty square tube.And the adhesive connection mode has a bad influence on the damping performance of square tube filled with foam aluminum.

Key words: foam aluminum, filling structure, damping, square tube
