Dr. Blough’s research includes dynamic measurement problems, developing new digital signal processing algorithms to understand NVH type problems and ways to improve the NVH characteristics of virtually any machine. He has made measurements on items as small as individual turbine blades to items as large as 45m diameter radio telescopes and many machines in between including automobiles, snowmobiles, M1 tanks, locomotives, and appliances. He has worked on automotive and snowmobile powertrains and other vehicle components to make them quieter. Currently, he is researching the implementation of active noise control systems in passenger vehicles.
Dr. Blough developed order tracking algorithms for processing data on rotating machinery that are commercially licensed. Additional digital signal processing projects have included Kalman Filter development for a specific automotive application
and Sound and Vibration Quality Jury and metric studies.
Dr. Blough is well versed in nearly all experimental NVH techniques including Modal Analysis, Transfer Path Analysis, Time-Frequency analysis, etc. He routinely teaches many of these techniques in the classroom and industry short courses. He also has experience in FEA and multi-body dynamics modeling.
