Abstract

This project is carried out to study about the energy absorption of the bicycle safety helmet during the impact with the rigid wall surface using simulation software. There are several impact positions that arc considered in this analysis which are frontal, side and top impact. The different type of impact position wi 11 give the different value of energy absorption due to several factors which are the material used, the area of contact, force on loading and so on. The project is carried out by using the ABAQUS/ Explicit 6.8. The existing model of helmet is modeled in the CA TIA V5R l 0 is imported into ABAQUS/ Explicit 6.8 through the IGES file consist of CAD data. The impact simulation of bicycle helmet is simulated and analyzed in the ABAQUS/ Explicit 6.8 to find the energy absorption of the bicycle helmet during impact with the flat rigid wall surface. The result and simulation is then compared with the existing research data. It is found that the top impact gave higher energy absorption compared to front and side impact.
