Crash analysis of racing car nose cone subjected to full frontal impact
Nuraini Abdul Aziza1, Norzima Zulkifli2, Amar Ridzuan A. Hamid3.
Racing a car involves high-speed and having high possibility to crash either among the
racer or hitting the bench. Concerning the driver safety, impact structures such as nose
cone is designed to absorb the race car kinetic energy to limit the decelerations acting on
the human body. In this study, analysis of different type of nose cone material were
conducted. The objective is to find the highest specific energy absorption (SEA) based on
three different materials which are mild steel, aluminium and composite material. The nose
cone was modelled using CATIA V5R16 while the crash simulation was done using LS-DYNA
and LS-Prepost software with an average velocity of 80km/hour according to United States
New Car Assessment Program (US-NCAP) frontal impact velocity and based on European
Enhanced Vehicle-safety Committee. The simulation results show that fiberglass E with
thickness of 2.6 mm and lay-up configurations of [0°/30°/60°/90°/120°] give the highest
internal energy and specific energy absorption of 41.28845 kJ and 6.9104 kJ/kg. This
concludes that fiberglass E is a suitable material to build a lightweight structure compared
to steel and aluminium.
