Indholdsfortegnelse:
- Automotive door systems are critical structural components influencing vehicle durability, fitment quality, safety, and customer perception. Door sag remains one of the major structural issues caused by gravitational loading, hinge deformation, manufacturing tolerances, and repeated operational cycles. Over the years, Computer Aided Engineering (CAE) and Finite Element Analysis (FEA) have become important tools for evaluating door stiffness, hinge behaviour, and deformation characteristics during vehicle development. This review paper summarizes research related to automotive door sag analysis, hinge durability, fatigue prediction, structural optimization, and reinforcement design methodologies. Various analytical, numerical, and experimental approaches adopted by researchers are critically reviewed. Reported studies show that finite element methods provide effective prediction of stress distribution and sag deformation while significantly reducing development time and prototype cost. However, limited research focuses on system-level sag analysis under multiple opening conditions integrated with analytical benchmarking and reinforcement optimization. The review highlights the importance of combining CAE-driven methodologies with practical design optimization strategies to develop lightweight, durable, and cost-efficient automotive door systems.
