Grad Seminar: Steven Shaw Dec. 2, ME 161 4:30 Torsional Vibration Absorbers for Rotating Machinery

[cid:image005.png@01CB8FBC.5FE94DA0] Mechanical Engineering Graduate Seminar [cid:image006.jpg@01CB8FBC.5FE94DA0] Thursday, December 2, 2010, ME 161 4:30 p.m. Torsional Vibration Absorbers for Rotating Machinery - from Symmetric Bifurcations to Advanced Engine Technologies Steven W. Shaw Department of Mechanical Engineering Michigan State University East Lansing, MI 48824 Abstract In this seminar I will describe results from our research on centrifugal pendulum vibration absorbers, which are used to attenuate engine-order torsional vibrations in rotating machines. These absorbers are well suited for reducing automotive powertrain vibrations, which are particularly troublesome during low-speed high-torque operation. One can improve fuel economy by attenuating these vibrations, for example, by enhancing low-speed torque converter lockup, or expanding operating ranges for cylinder deactivation in variable displacement engines. This presentation will explain the basic operation of pendulum absorbers, provide an overview of their rich nonlinear behavior (which includes symmetry related dynamic instabilities), and demonstrate how one can use our fundamental understanding of their dynamic response to help design effective absorber systems. I will outline our contributions to both basic and applied research, which includes predictive analysis, computer simulations, controlled experiments, and successful tests on automotive engines.

The work is currently funded by an NSF GOALI project and Chrysler Challenge Funds. Short Bio Steven W. Shaw is a Professor in the Department of Mechanical Engineering at Michigan State University. He received an A.B. in Physics (1978) and an M.S. in Applied Mechanics (1979) from the University of Michigan and a Ph.D. in Theoretical and Applied Mechanics (1983) from Cornell University. He has held visiting appointments at Cornell, the University of Michigan, Caltech, the University of Minnesota, the University of California-Santa Barbara, and McGill University. His interests are in dynamical systems and mechanical vibrations, with applications to vibration absorbers, micro- and nano-scale resonators, and structural vibrations. Steve currently serves in editorial capacities for the ASME Journal of Vibration and Acoustics and Nonlinear Dynamics. He is a Fellow of ASME and recipient of the ASME Henry Hess Award (1986), the SAE Arch T. Colwell Merit Award (1997), and the MSU Distinguished Faculty Award (2008).

"FoSpectroscopy of Individual Viruses Reveals DNA Storage Strategies and Structural Properties of Capsids Arce nd Virions" November 11, 2010 BNC, 1001, 3:30-4:30pm Pedro. J. de Pablo Departamento de Física de la Materia Condensada Universidad Autonoma de Madrid, Madrid, 28049 Madrid, Spain Microscopy in buffer conditions we performed nanoindentation experiments on a variety of bacteriophages and eukarytoric viruses. In the spherical virus Minute Virus of Mice (MVM) we discovered that the DNA molecule exerts an architectural role by increasing the stiffness of the virus on the 3 and 2-fold symmetry axes (1). This mechanical reinforcement is a consequence of the interaction between crystallographically visible, short DNA patches and the inner capsid wall, and apparently does not build internal pressure inside the virus. We have further manipulated the virions stiffness by protein engineering the junctions between the DNA and the capsid-wall. (2) Preliminary experiments performed on f29 bacteriophage proheads reveals built-in stress of the viral shell which behaves counter-intuitively different from standard continuum elasticity predictions. In addition, the comparison of empty and full DNA viruses results in a different stiffness which can be attributed to the internal pressure provided by the DNA of about 70 atm. We have also isolated the effect of capillary forces on single viral particles during desiccation processes (3). [1] PNAS 103, 13706 (2006). [2] PNAS 105, 4150 (2008). [3] PNAS 106, 5475-5480 (2009). Dr. Pedro José de Pablo Gómez is currently Associate Professor at the Universidad Autónoma de Madrid, Condensed Matter Department, Spain. Prior to joining the Universidad Autónoma de Madrid as a faculty member, he was a postdoctoral fellow at the Vrije Universiteit, Amsterdam, the Netherlands from 2001-2003. He earned his PhD at the Universidad Autónoma de Madrid in 2000, and also holds a B.S in Physics from the same University. During his doctoral studies, Dr. De Pablo spent 6 months as a research visitor at Purdue. Dr. De Pablo's research focuses on novel Atomic Force Microscopy methods to study multi-disciplinary problems in (a) physical virology, especially structural and mechanical studies of viruses in air and in buffer conditions, including bacteriophages P29, T7, and eukaryotic viruses, minute minute virus of mice (MVM) and adenovirus, (b) Detection of kinesin transport on microtubules, mechanics of microtubues, and (c) Electronic transport in single molecules.
