Description: This paper presents the development and application of a smart, flexible, vertical cantilevered beam system for experimentation and demonstration of vibration system modeling as a reinforcement to undergraduate dynamics education. Focusing on the difficult concepts of transfer functions and frequency domain based analysis, the beam system aids students in grasping basic vibration system concepts by allowing them to analyze and manipulate real system data collected through a simple and inexpensive piezoceramic-based data acquisition and actuation system. Students observed and analyzed the dynamic responses of a flexible aluminum beam subjected to various input signals to draw conclusions and relationships between system input and system response through the use of Bode diagrams, relationships often difficult for students to appreciate without experimental experiences. Results from post-demonstration student surveys indicate that the students found the demonstrations of the flexible beam system to be exceptionally effective in improving and motivating learning in their courses, with 94% of student responses rating the beam system as effective or very effective in various aspects of the demonstration.
