Inertial Amplification in Vibration Isolation Systems and Phononic Band Gap Structures

 

Dr. Çetin Yılmaz
Boğaziçi University, İstanbul, Turkey


Abstract:

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.
