The lightweight superstructures are designed for electric-based vehicles. The concept of crashworthiness is introduced to maintain the safety of the lightweight superstructures. The criteria for crashworthiness are developed by using international safety regulation. The multi-cell platform is proposed for designing a crash box system to improve the crashworthiness and energy absorption performance of electric vehicles. The multi-cell platform can increase the energy absorption of the crash box. There are several multi-cell configurations being studied, such as cruciform shape, H-shaped, T-shaped, and Y-shaped. The multi-cell columns are subjected to quasi-static and low-speed axial loading. The simulation results show that the multi-cell configurations have different effects on energy absorption capability. Increasing the number of cells and intersection can result in higher energy absorption but detrimental due to peak force. It is found that the optimum crash box system is the H configuration cross-section.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Absorption performance,Axial impact,Crash box,Different effects,Energy absorption capability,Light-weight constructions,Multicell,Safety regulations[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]axial impact,crash box,crashworthiness,energy absorption,multi-cell[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]ACKNOWLEDGMENT was funded by MENRISTEK[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ICEVT48285.2019.8993961[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
