The objective of this thesis is to study theoretically and experimentally the dynamic response of an articulated structure based on beam and bar elements that is used as a simplified model of an articulated subsonic aircraft wing, and whose geometry is modified through a proposed actuation system analogous to the one found in an articulation of the human finger. Inspired in the extension and flexion systems of the human finger, the proposed actuation system consists of tensioning cables that work as artificial tendons to modify both stiffness and geometry of the structure in study. By enabling articulated wings to adapt an optimal position during all flight phases, the proposed actuation system would generate more efficient operations and a smaller carbon footprint than rigid wings, which are typically designed to perform optimally at cruise only. To study the dynamic response of an articulated structure with artificial tendons, three mathematical models were developed, and their equations of motion were formulated. Additionally, an experimental model was built, and three groups of experiments were designed to evaluate the effects of the variation in tension and wing position (extension/flexion) upon the natural frequencies of the structure. Based on the assessment of theoretical and experimental results, it was concluded that the mathematical models proposed for the articulated structure actuated with artificial tendons are adequate to predict the dynamic response of the structure, and that variations in tension and wing position (extension/flexion) reconfigure the natural frequencies of the dynamic system.
