Abstract
According to the problem that the thickness change of the square cylinder as energy-absorption component affect energy-absorption characteristics of the square cylinder, this paper researches that the thickness of the square cylinder for energy-absorption component of the square cylinders influence through theoretical analysis and using numerical calculation method. The theoretical part in this paper analyze local deformation of the square cylinder theoretical model as a result of axial compression ,and in the numerical simulation part this paper simulate the dynamic response of the thin wall square cylinder model structure , thereby research the thickness change of the square cylinder influence on energy-absorption characteristics of the square cylinder. At last, the change curve of the force-deformation is drawn with the change curve of force-peak load, and it is obtained law that the thickness of the square cylinder influence on energy-absorption characteristics the square cylinder and optimum thickness.
