Engineering Summary: Sectional overhead garage door assemblies are critical mechanical systems in industrial and commercial facilities where frequent operation and spatial constraints demand reliable and efficient solutions. These doors consist of multiple interlinked panels connected via hinges that allow smooth articulation along curved tracks during opening and closing cycles. The hinge regions are subjected to complex stress states arising from repeated bending and rotational motion, which makes them particularly vulnerable to fatigue damage. In environments characterized by high-cycle industrial usage, these doors can undergo hundreds of thousands of cycles annually, significantly increasing the risk of fatigue-induced failures. Understanding the mechanical behavior during articulation, the fatigue mechanisms at play, and the … 続きを読む
