Abstract

There is an increase in demand for compressed natural gas vehicles in India. Due to the high gasoline prices and lack of electric vehicle infrastructure in India, compressed natural gas vehicles are the only feasible option. This research work focuses on the crashworthiness of a saloon car fitted with a compressed natural gas cylinder under rear-collision conditions. Four different candidate materials
of the same thickness are chosen for the cylinder based on strength and ductility i.e., AA6061, AA2024, mild steel, and A36 steel. The finite element analysis of the crash is performed in LS-DYNA by incorporating the Johnson-Cook material model parameters for the selected materials. The results are obtained from the crash analysis for the variation of the resultant force, kinetic energy, and
internal energy, and these results are compared for different materials. The cylinder made of A36 Steel has shown the least absorption of specific energy, and the least deformation is observed in the cylinder compared to other materials.
