Abstract

Due to the low manufacture cost and easy installation, tubal structures are common utilized as energy absorbers in automotive and other engineering industries. In the present work, four novel reinforced multi-corner columns (RMCs) were investigated using numerical, theoretical, and experimental approaches, results showed that the RMCs had prominent crushing performances compared with other typical multi-cell tubes. Furthermore, the TOPSIS method and multi-objective optimization were conducted to find the best structure and its optimal design parameters, respectively. The optimized column showed excellent crashworthiness capacities and had great potential to be used as energy-absorbing components in engineering applications.

摘要

由于制造成本低且易于安装，管状结构通常用作汽车和其他工程行业的能量吸收器。在目前的工作中，使用数值、理论和实验方法对四种新型增强多角柱 (RMC) 进行了研究，结果表明，与其他典型的多细胞管相比，RMC 具有突出的抗压性能。此外，TOPSIS 方法和多目标优化分别进行了寻找最佳结构及其最佳设计参数。优化后的柱子表现出优异的耐撞性能，在工程应用中具有作为吸能部件的巨大潜力。
