SUMMARY:Arion Pons (Hebrew University of Jerusalem\, Israel): Elasticity\, 
 Energy\, and Nonlinear Resonance in Insects and FW-MAVs
DESCRIPTION:Arion Pons: Insect flapping-wing flight\, alongside many other 
 biological and biomimetic modes of locomotion\, has a vibrational characte
 r: it is founded on patterns of periodic motion\, in stark contrast to the
  non-periodic patterns utilised by artificial locomotive structures (e.g.\
 , propellors). As we try to analyse and understand this vibrational charac
 ter\, the phenomenon of resonance hovers uneasily in the background. Reson
 ance offers the prospect of significant energy savings\, and performance i
 mprovements\, based on close tuning between frequency\, elasticity\, mass\
 , and other structural properties\; but details are cloudy\, especially wh
 en exploring the complex nonlinearities present in real locomotive structu
 res. In this talk\, I will discuss how new theoretical results in nonlinea
 r dynamics paint a new picture of the role of resonance in these vibration
 al modes of locomotion\, with a particular focus on insect flight and flap
 ping-wing micro-air-vehicles (FW-MAVs). These results challenge several co
 re assumptions about how resonant systems behave. I will demonstrate i) ho
 w even simple vibrational locomotive systems have multiple different reson
 ant states\, motivating new approaches to the analysis of insect thoracic 
 resonant properties\; ii) how it is possible to access resonant states usi
 ng only unidirectional actuation\, motivating new designs of FW-MAV\; and 
 iii) how it is possible to deviate from the resonant frequency and still m
 aintain resonant energetic optimality\, motivating new interpretations for
  insect flight control behaviour. Together\, these results provide new ins
 ight into the fundamental relationship between nonlinear resonance\, elast
 icity\, and energy in insects and FW-MAVs\, and provide new qualitative an
 d quantitative tools for the design and analysis of other forms of vibrati
 onal locomotive system.\nIOSSB Seminar
