Investigation on Design and Analysis of Passenger Car Body Crash-Worthiness in Frontal Impact Using Radioss 2020-28-0498

Increasing advancement in automotive technologies ensures that many more lightweight metals become added to the automotive components for the purpose of light weighting and passenger safety. The accidents are unexpected incidents most drivers cannot be avoided that trouble situation. Crash studies are among the most essential methods for enhancing automobile safety features. Crash simulations are attempting to replicate the circumstances of the initial crash. Frontal crashes are responsible for occupant injuries and fatalities 42% of accidents occur on frontal crash. This paper aims at studying the frontal collision of a passenger car frame for frontal crashes based on numerical simulation of a 35 MPH. The structure has been designed to replicate a frontal collision into some kind of inflexible shield at a speed of 15.6 m/s (56 km/h). The vehicle’s exterior body is designed by CATIA V5 R20 along with two material properties to our design. The existing Aluminum alloy 6061 series is compared with carbon fiber IM8 material. The simulation is being carried out by us in the “Radioss” available in “Hyper mesh 17.0” software. The energy conservation and momentum energy absorption are carried out from this dynamic structural analysis.
