In order to improve the efficiency of energy absorption, a reasonable induced structure was designed to produce positive impact on energy absorption components. A circular arc induced structure was designed for thin-walled pipe, and its energy absorption characteristics were studied under different length to diameter ratios, diameter thickness ratios and the depth of the groove. The simulation results showed that the energy absorption moved in opposite direction with the change of length to diameter ratio and diameter-thick ratio. And with the increase of groove depth, the initial crushing load decreased. The initial load was efficiently reduced by using groove induced structure under different conditions, and a relatively stable crushing load platform was obtained.
