Description
Bastián Sáez and co-authors design panels that calm vibration in 2025. Light structures in planes and cars shake, which breeds noise and wear. Perforated panels can block vibration in set bands, but uniform holes limit tuning. The team lets each hole in a cellular panel take its own size.
Computer models of the panel were paired with a swarm search algorithm. The search tuned hole sizes to hush target frequency ranges. Lab panels were then built and shaken to check the design. Finer control over each hole may yield quieter cabins and longer lasting structures.
