Design and Development Of Energy Absorber In Automobile For Velocity Impact

Abstract Automotive frontal collisions generate high impact forces that can cause severe damage to vehicle components and increase the risk of passenger injury. To improve crashworthiness and energy absorption capability, a novel composite energy absorber based on a double half-cylinder configuration was designed and analyzed for low- and medium-velocity impact conditions. The proposed absorber was developed using composite materials and evaluated through finite element analysis (FEA) under frontal collision loading. A mathematical model was formulated to estimate impact energy and impact force for various vehicle velocities. For a vehicle mass of 2630 kg and an impact velocity of 25 km/h, the calculated impact energy was 63.3 kJ and the corresponding impact force was approximately 316.7 kN. Numerical simulations were performed to evaluate total deformation, equivalent stress, strain distribution, and energy absorption characteristics of the proposed design. The results demonstrated that the double half-cylinder absorber effectively reduced impact-induced stresses while increasing energy absorption capacity compared with conventional bumper energy-absorbing structures. The proposed configuration offers improved crash performance, lightweight construction, and enhanced passenger safety for automotive applications. The study confirms the suitability of composite-based energy absorbers as a cost-effective solution for low- and medium-velocity vehicle impacts.
