Inertial Amplification in Vibration Isolation Systems and Phononic Band Gap Structures
Dr. Çetin Yılmaz
Boğaziçi University, İstanbul, Turkey
Vibration isolation is a well-established field with applications ranging from aerospace industry to home appliances. However, achieving vibration isolation at low frequencies by just passive means is an enduring problem for stiff and lightweight structures. I will demonstrate the underlying fundamental problem and propose solutions that make use of anti-resonance generation via inertial amplification. The second part of the talk is about formation of phononic band gaps in periodic media, which is in the realm of condensed matter physics. Yet, this field is also explored by engineers aiming to design structures that impede the propagation of elastic waves in certain frequency ranges. I will highlight the benefits of inertial amplification to the generation of phononic band gaps.
Çetin Yılmaz received his B.S. degree in Mechanical Engineering from Boğaziçi University in 2000. He pursued his graduate study at University of Michigan between 2000 and 2005. In 2001 and 2002 he completed his M.S. degrees in Mechanical Engineering and Mathematics, respectively. In 2005 he received his Ph.D. degree in Mechanical Engineering. Between 2005 and 2007 he worked as a post-doctoral researcher at University of Michigan. Currently, he is an Assistant Professor at Boğaziçi University. His research interests include multi-body dynamics, vibrations, and design. In particular, vibration isolation systems, phononic band-gap structures, passive anti-resonance generation methods, design of displacement amplifiers and motion converters, optimization.
