| Abstract: | The thin walled metal energy absorption characteristics are summarized by the numerical simulation on the energy absorption characteristics of thin walled metal tube. The indices such as energy absorption ability, mean crushing load, and ideal energy absorption efficiency are used to comprehensively evaluate the energy absorption characteristics of thin walled metal tube. An optimization scheme is proposed for the thin walled metal tube energy absorber. The results of comparison and analysis indicate that the optimization scheme can greatly improve the ideal energy absorption efficiency of the energy absorber and reduce the buffering force fluctuation in the work process. |
