 abstract={The increasing adoption of unmanned platforms in sectors such as defense, agriculture, logistics highlights critical challenges, including traversal capability and collision resistance in unstructured terrain. This study investigates the crashworthiness of the developed TAERO UGV using Finite Element Method (FEM) analysis. The structural components critical to collision energy absorption were identified and analyzed. Descriptions of the LS-DYNA simulation model, material properties, and boundary conditions are provided. The primary objective was to numerically assess the bumper's performance during impact, considering the vehicle's operational speeds and crumple zone. An optimized numerical model was introduced to efficiently simulate vehicle collisions, focusing on key structural elements. Various scenarios were simulated to examine deformation, stress distribution, and bumper behaviour. Presented numerical analysis indicate that impacts with typical obstacles, like tree trunks in unstructured terrain, cause minimal damage, not affecting the vehicle's operational capability. Minor bumper damages, such as dents, varies with speed—more noticeable at higher speeds, while almost imperceptible up to 25 km/h. The stress distribution highlights the role of side components in energy absorption and structural deformation. The results confirm the vehicle's structural integrity and provide valuable data on its operation performance in complex environments during specialized missions.},
