Additively manufactured (3D-printed) oboe reeds offer a promising solution to the challenges of quality inconsistency and limited durability associated with traditional cane reeds.Our prior work has established that the acoustic characteristics of these reeds can be tuned by modifying their mechanical compliance (the inverse of bending stiffness) through the integration of an internal support structure.The present study builds upon this foundation by employing topology optimization, a computational design method, to systematically engineer the reed's internal geometry.Our primary objective is to generate a structure that maximizes bending stiffness without increasing the overall mass.The optimized topology derived from our simulations deviates significantly from the simple, uniform structures previously investigated.We hypothesize that this new geometry will exhibit enhanced bending stiffness.This study aims to verify this hypothesis through numerical simulations and to determine, via acoustic analysis, the extent to which this enhanced stiffness directly improves acoustic performance.Ultimately, this research seeks to shift the design of synthetic reeds from a traditional, empirical approach to a systematic, computer-aided optimization framework.This method holds promise as a cornerstone technology for the on-demand production of a wide variety of reeds, each customized to meet the unique needs of the performer.
