<正>An experimental investigation was carried out to study the energy absorption characteristics of thin-walled square tubes subjected to dynamic crushing by impact loading to develop the optimum structural members.[1-5]Here,the controller is introduced to improve and control the absorbed energy of thin-walled square tubes in this paper.When the controller used,the experimental results of crushing of square tubes controlled by the controller's elements showed a good candidate for a controllable energy absorption capability in impact crushing.
