Abstract
This research focuses on improving vehicle safety by developing a new spring-based energy absorption system for the front bumper of a Bolero vehicle. The goal is to reduce the severity of frontal collisions by absorbing a significant portion of the impact energy. The proposed system comprises a helical compression spring, a mounting bracket, and a chassis member. This design aims to absorb 30-35% of the energy impact, reducing the deceleration rate and minimizing the shock transmitted to the passenger cabin. To visualize the system and estimate its energy absorption capabilities, a 3D CAD model and analytical calculations have been performed. Further analysis using finite element methods will provide a more detailed understanding of the deformation behaviour of the bumper and spring, as well as the energy absorption capacity of the shock absorbing. Future work will involve refining the design, conducting detailed analysis, and evaluating the performance of the system through rigorous testing. This research has the potential to significantly enhance vehicle safety and mitigate the risks associated with frontal collisions. Major Findings: A novel spring-based impact energy absorption system was proposed to reduce the severity of frontal collisions by 30-35 %. Finite element analysis was conducted to assess the system's deformation behaviour and energy absorption capacity. The four-damper system demonstrated a 42.44% reduction in maximum deformation compared to a plain bumper. The proposed system has the potential to significantly enhance vehicle safety.
