Investigation on Crash Analysis of a Frontal Car Bumper

摘要

A new design and development of a bumper are proposed for a Hyundai i10 car. The developed bumper is analysed for crash worthiness. The performance is compared with different bumper materials, such as ABS, E-glass epoxy resin, and polyamide-30% glass fibres. In this work, impact and collision of a car are simulated and analysed using ANSYS explicit dynamics. The car is modelled using Pro-e and exported to ANSYS. The bumper is first analysed using the basic design and material. Thereafter, the analysis is done with the bumper with added reinforcement and change in material. Two cases of impact have been considered: they are full frontal impact barrier and half impact barrier. The purpose of the frontal crash analysis is to understand the impact of the crash. The new bumper design must be versatile enough to reduce the rider injury and keep intact throughout low-speed impact besides being stiff enough to dissipate the K.E. in high-speed impact. The bumper is a key structure for absorbing energy of collisions. The crash analysis simulation and results can be used to assess both the crashworthiness of current bumper and to analyse ways to boost the design.
