Event: ME Fall 2012 Seminar Series: 'Modulation Phenomenon Observed in Mechanical Systems,' Murat Inalpolat, GE Global Research Center, Structural Mechanics and Dynamics Laboratory
Location: UTEB 150
Time: 02:00 pm
Details of Event:
Abstract: Modulation phenomenon has been frequently associated with electronic communications and intentionally used for transmitting information. However, modulations observed in mechanical systems are mostly generated unintentionally due to manufacturing tolerances, manufacturing errors and sometimes even due to the way generated signals being received. In this talk, modulation phenomenon observed in mechanical systems will be discussed along with real life examples. Planetary gears will be used as a specific application example to demonstrate the phenomenon. Benefits of understanding the phenomenon will be discussed as resulting effects of modulations on system level vibration, noise and fatigue is yet to be understood in a complete way. Analytical and experimental investigation of planetary modulations will be demonstrated to clarify some of the associated phenomena.
Biographical Sketch: Dr. Murat Inalpolat is a mechanical engineer for General Electricís Research and Development Center. He has been with GE since 2010, leading and supporting different research and development projects for wind energy, aviation, transportation and steam turbine businesses with focus on energy, efficiency, dynamics, diagnostics and power density improvement of rotating machinery. Main emphasis is on gears, rolling element and fluid film bearings, rotordynamics and associated mechanical power transmission systems as well as on vibration and noise reduction related technologies. Previously, he held positions at The Ohio State University first as a research associate and then as a postdoctoral fellow working on geared system dynamics and noise. He received his PhD in Mechanical Engineering from The Ohio State University. He holds M.S degrees both from The Ohio State University and Middle East Technical University, Ankara, Turkey. His current research focuses on the influence of manufacturing uncertainties and errors on the reliability, efficiency and dynamics of rotating machinery.
