Jerry H. Griffin Professor,  Mechanical Engineering   Director, GUIde Consortium    Carnegie Mellon, 1980-present    Research areas:  Vibrations, damping, gas turbines, fatigue, dynamics and friction.    Ph.D. 1973, California Institute of Technology; B.S., M.S. 1969, University of South Florida. e-mail: jg9h+@andrew.cmu.edu Home Page Professor Griffin's research includes the areas of linear and nonlinear vibration. He has special interests in predicting the amplitudes of vibratory response of rotating equipment, especially gas turbine engines and drive trains. Recent projects include developing predictive models of damping due to microslip at friction interfaces, an improved understanding of high frequency tip mode vibration in low aspect ratio blades, reduced order models of blade mistuning including aerodynamic effects and friction, more computationally efficient methods for computing the forced response of packeted blades, new mathematical methods for analyzing the effect of periodically varying inertia and stiffness on system response and more reliable methods of predicting torsional vibration in drive trains.  A number of Professor Griffin's research projects are developed in cooperation with two industrial and government consortia. He formed the GUIde Consortium on the forced response of bladed disks and is Director of the GUIde sponsored CMU Center for Bladed Disk Structures Research and Technology.  The Torsional Vibration Consortium (TVC) developed software for computing the torsional vibratory response of drive trains.   Back to main faculty page Overview | Undergraduate studies | Graduate studies | Research Department News | Alumni Resources Related links: Carnegie Mellon front door | Admissions office Carnegie Institute of Technology | Pittsburgh
