This thesis examines the design and performance eva‎luation of the seatbelt anchor and seat of a small electric vehicle of class L6e using finite element analysis (FEA). Research on the design and analysis of the seatbelt anchor and seat components is particularly significant due to the fundamental safety challenges for occupants in electric vehicles, especially during collisions. With the increasing use of electric vehicles and the need to optimize their weight and efficiency, appropriate design of anchors can help reduce accident-related injuries. Initially, a precise 3D model of the seatbelt anchor, seat, and related components was designed using CATIA software. This model was then meshed using HYPERMESH. Subsequently, finite element modeling for strength testing of the seatbelt anchor was performed using ABAQUS software in accordance with ECE-R14 standards. Finally, stress analysis and deformation assessment of the seatbelt anchors were conducted. Additionally, modeling to assess the strength of the seat anchor was carried out using LS-DYNA software per ECE-R17 standards. The results of the finite element analysis indicated that the proposed design can withstand loads under various collision conditions and is deemed safe for occupants. This research contributes to improving the safety and performance of electric vehicles and can serve as a reference for similar design and analysis in the automotive industry.
