X-shape Bio-inspired Structures

Scissor-like structured platform for vibration suppression.

Bio-inspired leg/joint design of robots.

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.

Special Features and Advantages
• Inspired by animal leg/limb structures, internal layer of cranial bone and head bone structure of Swordfish
• Adjustable nonlinear damping and stiffness design
• Passive suspension which do not require external power supply
• Good loading capacity and equilibrium stability
• Tunable and foldable design

Applications
• Robot development
• Vehicle’s suspension system
• Space mission
• Packing and protection materials
