X-shape Bio-inspired Structures


Scissor-like structured platform for vibration suppression.

The X-shaped bio-inspired structures are novel designs of passive vibration isolation systems. Using only linear spring and damping components, the X-shaped structures can achieve superior nonlinear vibration isolation. The vibration isolation systems can be with n-layers of X-shaped structures to suit different applications, such as leg/joint design of robots, limb-like structured suspension for mobile robots with track, protection of high-precision machinery, vehicles’ suspension, space launch and on-orbit applications, etc.
