Experimental modal analysis (the process of determining the dynamic parameters of a system through force excitation and sensing of the subsequent dynamic response) can be used to investigate the dynamic parameter differences between acoustic instruments. Various techniques to excite and sense the dynamic responses of a structure exist, such as manual roving impact hammer excitation; however, a standardized, automated approach of conducting experimental modal analysis would benefit these investigations of acoustic instruments. I present through this thesis an automated CNC-based roving impact platform for experimental modal analysis. The platform enables four-axis positioning of the impact hammer on the surface of the instrument and automated closed-loop control actuation of the impact hammer for accurate and repeatable excitation. The platform's movement and actuation are controlled through a suite of open-source software to keep accessory costs low and accessible to both researchers and instrument builders. Through this work, I demonstrated that the CNC roving impact platform increases the precision and accuracy of positioning and repeatability of impact hammer excitation compared to traditional hand actuation.
