    Abstract
  • As the main energy absorbing component of bearing and collision in the automobile and aviation industry, the hat-section beam structure absorbs energy through plastic deformation of its own structure, which is the main criteria for previous safety design. Therefore, it is of great significance to study the deformation characteristics and energy absorption characteristics of the hat-section and thin-walled beam structure under impact load. In this paper, the axial dropping impact tests of DP780 and DP980 duplex steel with hat-section thin-walled beam structures are carried out with a dropping hammer designed by ourselves, and the maximum displacement, peak load, deformation modes and energy absorption are obtained. The results show that the plastic buckling of the upper part of the specimen is formed and the deformation of the lower part is unobvious for DP980 and DP780 hat-section beams under impact loads. The DP980 hat-section beam has less impact deformation and higher residual height, which can be used as the protection structure of anti-impact deformation. The DP780 hat-section beam has more wrinkles produced by final buckling deformation, and its impact time increases and the peak load is much lower, which can be used as the protection structure of anti-impact load. The energy absorption capacity of the DP980 hat-section beam is similar to that of the DP780 hat-section beam. The results provide the basis for the selection of anti-impact performance with thin-walled structure.
