Investigating New Functionality of Origami-inspired Structures / 折りたたみ構造の新機能の創出
Origami-inspired deployable structures are primarily known for their ability to undergo large shape changes during deployment and contraction. However, the potential of these structures extends far beyond shape transformation. Their unique mechanical characteristics offer opportunities for a wide range of functional applications.
For example, deployable structures exhibiting a torsional buckling pattern are known to possess bistable behavior. We have utilized this bistability as a nonlinear spring element and developed quasi-zero-stiffness vibration isolators. At first glance, it may seem surprising that origami-inspired structures can function as vibration isolators. However, once we move beyond the preconceived notion that origami is merely paper folding and instead examine its mechanical and dynamic behavior from a scientific perspective, its broader engineering potential becomes evident.
This study was financially supported by the Grant-in-Aid, Ministry of Education, Culdture, Sports, Science and Technology (MEXT) of Japan, and a part of the research achievements is introduced to the public on MEXT website.
We are currently investigating further applications of origami-inspired structures, including sound attenuators in acoustics and fluid transport pipes in fluid dynamics.
