Abstract

Courses in vibration taught at Rose-Hulman Institute of Technology are designed to blend classroom discussion of the science of vibration with practical, hands-on applications. The laboratory portion of the undergraduate course in vibration focuses on two areas: (1) system identification for single- and multi-degree-of-freedom systems in the frequency domain through sine-sweep shake testing; and (2) identifying natural frequencies and mode shapes for continuous systems via experimental modal analysis using frequency response data collected through a roving hammer test. Modal analysis is performed using an in-house MATLAB-based program known as Easy Modal Analysis Program (EMAP). The goals of this thesis are two-fold: (1) to create new laboratory exercises to allow students to explore elements of base motion, rotating unbalance, and structural health monitoring; and (2) to expand the functionality of EMAP to allow students to explore the damping characteristics of a system via different methods. The development of these additional laboratory exercises and the expanded functionality of EMAP serve to broaden the students’ practical knowledge of topics in vibration measurement and analysis.
