Energy Absorption Analysis of Circular Tube of The Foam for High-Speed Train
This paper discusses the outcomes concerning the crushing properties of aluminum foam–filled tubes with a circular cross-section. The review assessed the impact of placing aluminum foam in single- and double-walled circular. A parametric evaluation was performed concerning the circular with the single- and double-walled variants. Validation results were contrasted against the documented experimental data, and a noteworthy alignment was observed. The foam strain rate is vital in regulating the crushing properties of the foam-loaded circular, and this factor must be considered. The outcomes also indicate the interaction between the circular wall and foam core has a varying deformation category and specific energy absorption. Foam loading had a similar effect concerning double-walled circular loads with foam. Moreover, evaluations were performed to determine the impact of core thickness and impact velocity on the crashworthiness performance. Further, it was discovered that a rise in core thickness for double-walled foam-loaded circular enhances crushing characteristics until the walls still interact. Subsequently, any rise in core thickness leads to the response aligning more with the single-walled circular energy absorber of a high-speed train.
期刊介绍:
WSEAS Transactions on Applied and Theoretical Mechanics publishes original research papers relating to computational and experimental mechanics. We aim to bring important work to a wide international audience and therefore only publish papers of exceptional scientific value that advance our understanding of these particular areas. The research presented must transcend the limits of case studies, while both experimental and theoretical studies are accepted. It is a multi-disciplinary journal and therefore its content mirrors the diverse interests and approaches of scholars involved with fluid-structure interaction, impact and multibody dynamics, nonlinear dynamics, structural dynamics and related areas. We also welcome scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations.
