Improvement of crashworthiness of pickup vehicle for frontal and side collision using Finite Element analysis

This study aimed to enhance the existing vehicle’s structural reaction to a frontal and side impact collision. Energy-absorbing parts, a sturdy frame design, and enhanced crash performance are used to produce improvements based on the outcomes of the current model. When conducting the analysis, 3D modeling is done using CATIA, and FEM analysis is done using LS-DYNA. After adjustment, the ability to stabilize the momentum, the impact force during a crash, and the relation between internal energy and deformation is discussed; in doing so, the impact force is reduced by 7.82% and a 3.52% increment of energy is absorbed during a frontal collision. The side structure of the modified model also provided additional 162 mm space protection for the occupant, a reduction of impact force by 14.4%, and absorbed additional 7.6% energy. The new model generates more moment force that stabilizes fast as compared to the current, and also the relationship between energy absorbed and deformation is seen that with less deformation, the new model absorbs more energy. In conclusion, it can be claimed that the updated model considerably improved the pickup vehicle’s safety and crashworthiness without affecting the vehicle’s weight or appearance.
