Title: Mechanical metamaterial-based dynamic design and control
Abstract:
Inspired
by the perceiving principle of ultra-wideband acoustic signals in the cochlea,
a flexible coupling resonance low wideband mechanical wave control method of
"using softness to resist rigidity" was proposed. We have conducted
research on the design theory of lightweight and miniaturized equipment
parts/devices based on mechanical metamaterial, as well as methods for
improving low-frequency bandwidth performance, in response to the requirement
for improving the dynamic performance of equipment. Equipment design divided
into three levels, those are structural ontology regulation, boundary
modulation, and system integration. With the main line of mechanical wave
regulation of "using flexibility to resist rigidity", forming
systematic achievements in three aspects, those are structural ontology
flexible strong coupling regulation theory, metamaterial-based modulation and
efficiency enhancement of system boundary, and integrated application design
under engineering condition constraints.
