New Techniques in Experimental Structural Dynamics Using a Scanning Laser Vibrometer
Abstract
This instrumentation project was to develop new techniques in experimental structural dynamics for use with a Scanning Laser Doppler Vibrometer purchased with a grant from the AFOSR. A Laser Vibrometry Laboratory was established and the equipment has been used for structural health monitoring and modal analysis research, and teaching experiments. The research results obtained are helping to improve damage detection techniques for large structures, and the upper frequency range of modal analysis testing has been extended from previous limits of 20KHz to 200KHz for small structures. The laser equipment is bringing new research and attracting more students to A&T University, and is drawing attention from the community. An American Society of Mechanical Engineers tour showed the Laser Vibrometry Laboratory to engineers from local industry, and a number of outside faculty have also visited the laboratory. The local television station Fox 8 did a short story on research activities at A&T and included a three second part on use of the laser. An article on the laser award was also published in the Greensboro News and Record newspaper. The AFOSR grant to purchase the laser system has been a tremendous benefit to A&T university, the students, faculty, and the community.
