Abstract
Multi-cell structures and corrugated tubes illustrate excellent capacities. Besides, bamboo with continuously changing contours demonstrates superior impact-resisting capacities. As a result, a bionic multi-cell double corrugated (BMDC) tube inspired by bambusa bamboo can be an ideal energy absorber candidate. This study investigates the crashworthiness response of BMDC tubes. The basic numerical model was corrected using a physic experiment, followed by an investigation of BMDC tubes' energy absorption performance under axial loading, considering thickness and mass. Results indicate that te EA, MCF, SEA of BMDC-5 with 1.5 mm thickness are 2.13, 2.13, and 1.83 times higher than the BMDC-0, respectively. In addition, the BMDC-5 with 0.156 kg mass generates the highest EA, MCF, and SEA, which is 1.80 times higher than the corresponding BMDC-0, in the same mass scenario. Parametric analysis illustrates that amplitude and diameter desive influence the energy absorption characteristic. This study emphasized that BMDC tubes are innovative and practical, possessing excellent energy absorption performance.
