Abstract

Abstract—Crashworthiness criteria attention in structural vehicle has increased by government to make the road safer, leading towards to laws and investment to investigation. In order to improve the crashworthiness and energy absorption performance of electric vehicles, the multi cell platform introduced as application in designing crash box. Multi cell platform can increased the energy absorption of crash box. Designing multi-cell platform needs the cell configuration and the cell number. Various type of cell configuration and number show difference behavior. It is needs to be studied comprehensively in order to gain desired design criteria. This paper studied the behavior of various type of multi-cell platform. The configuration divided into cruciform shape, H-shaped, T-shaped and Y-shaped. The crash box subjected under axial load in low velocity of quasi-static mode. The simulation results show that the cell configuration and cell number have different results. Increasing the number of cell and intersection can result in higher energy absorption but detrimental due to peak force.

Keywords: multi-cell, crash box, axial impact, crashworthiness, energy absorption
