ANALYIS OF FRONTAL CRASHTEST FOR THE PERFORMANCE OF CRASHWORTHINESS OF PASSENGER VEHICLE USING HYPERMESH

This study presents an in-depth analysis of frontal crash tests conducted to evaluate the crashworthiness performance of a passenger vehicle. The primary objective is to assess the vehicle's ability to protect occupants during frontal collisions. The research encompasses various aspects of crashworthiness, including structural integrity and deformation patterns. The methodology involves the creation of a high-fidelity finite element model that accurately represents the vehicle's geometry and material properties. Crash simulations are performed using Hypermesh simulation tools to replicate real-world collision scenarios. This study focuses on a systematic approach to modeling and simulating frontal crashes using HyperMesh, emphasizing the software's capabilities in creating complex vehicle models with accurate material properties and boundary conditions. The analysis includes evaluating impact dynamics, deformation patterns, and energy absorption characteristics of vehicle components such as the body structure, chassis, and safety systems. These metrics are crucial in determining the vehicle's ability to absorb and dissipate impact energy, thereby minimizing injury risks to passengers. The findings from this study contribute to enhancing the safety and crashworthiness of passenger vehicles by providing valuable insights into structural design improvements and safety mechanisms. The findings show that while local structural improvements can help an automobile be more crashworthy, a significant modification in the car's crash box structure is necessary for further improvement.
