  Abstract

This study explores the dynamic behavior of macro-fiber composite (MFC) under varying voltage and curvature conditions, aiming to optimize its maximum displacement. We identified a direct relationship between applied voltage and displacement, with higher voltages leading to increased displacements. Concurrently, the natural frequency decreased as effective stiffness and electromechanical coupling changed. To measure maximum displacement, a novel sweep method was introduced and validated, demonstrating a low error rate and offering a reliable alternative to traditional techniques, particularly for curved or irregular structures. Further, the study revealed that curvature significantly impacts both the natural frequency and maximum displacement of MFCs. A critical curvature point was identified, where displacement behavior shifted, providing essential insights for optimizing MFC design and application. These findings contribute to a deeper understanding of MFC dynamics and open new avenues for applying the sweep method to other piezoelectric materials and complex geometries. This research sets the stage for future studies aimed at refining the sweep method for more precise and efficient use in advanced engineering applications.
