摘要：

To address the limitation of inflexible dimension parameters in thin-walled structures for ensuring energy absorption effectiveness, a design approach for a multi-tube combination of Corrugated Spacer Tubes (CST) based on a height difference staggered compensation method was proposed. The theoretical and finite element models of CST were established, and the accuracy of both models was validated through experiments. Based on the theoretical model, a design approach for the CST multi-tube combination was presented. By sequentially selecting the structural parameters of CST to induce stable and ...
