Abstract
A recently discovered sound production system (Aeroelastic Tymbal) located at the base of the hindwings of ermine moths produces bursts of ultrasonic clicks. The sound is produced when a ridge area on the aeroelastic tymbal buckles. The resultant sound has similar characteristics to that produced by the tiger moth, which in a certain genus is capable of jamming a bat biosonar. The biomechanical function of the aeroelastic tymbal is idealised by a simplified one-dimensional compliant mechanism, and the stability of the structure is evaluated using the modified Riks method. The purpose of this research is to take inspiration from evolved biological structures found in insects, for the development of adaptive and well-behaved non-linear structures.
