Development and Experimental Validation of a Bistable SMA Active Grill Shutter actuator

Bistable Shape Memory Alloy (SMA) actuators offer a promising solution for energy-efficient control in active aerodynamic systems such as Active Grille Shutters (AGS). By enabling discrete, reliable movements, such as 90° rotations, these actuators support adaptive airflow management based on driving conditions. To explore their integration into vehicle components, AGS elements were designed for manufacturability using Fused Deposition Modeling (FDM), well-suited for rapid prototyping and functional testing. The resulting components were successfully installed within a vehicle’s front bumper, demonstrating both aerodynamic effectiveness and structural feasibility. This approach highlights the synergy between smart materials and digital manufacturing in the development of next-generation adaptive aerodynamic components.
