ME-EM Graduate Seminar: Advances in Decoupling

sep25The ME-EM Graduate Seminar speaker on Thursday, September 25 at 4:00 in 103 EERC will be Dr. Daniel
Kawano from Rose-Hulman Institute of Technology – Mechanical Engineering – Engineering Mechanics Department.

The title of his presentation will be ‘Advances in Decoupling’.

Under certain restrictions on system damping, the equations of motion for a linear vibratory system may be decoupled into independent equations that reveal characteristic vibrational behavior. This seminar presents recent advances in the theory of decoupling that allow a vibratory system with general viscous damping characteristics to be exactly decoupled by a real, time-varying, eigenvalue-preserving transformation that generalizes modal analysis. The underlying physics of this decoupling transformation is explained, and the decoupling methodologies for various vibratory systems are discussed.

Daniel Kawano is an Assistant Professor of Mechanical Engineering at Rose-Hulman Institute of Technology in Terre Haute, Indiana. He received his B.S. degree in Mechanical Engineering from California Polytechnic State University (Cal Poly) in San Luis Obispo. Daniel obtained his M.S. and Ph.D. degrees in Mechanical Engineering, with a focus in dynamical systems, from the University of California at Berkeley. His research and academic interests include modeling, analysis, simulation, and testing of dynamical systems; experimental modal analysis; numerical solution of differential and differential-algebraic equations; and pedagogy in engineering education. Daniel’s current research and activities involve exact decoupling of damped, linear vibratory systems,
and the use of online videos, web-based interactive demonstrations, and online
learning platforms to enhance student learning in dynamics. He is also the faculty advisor for Rose-Hulman’s Formula SAE competition team, Rose Grand Prix Engineering.
