Bio-inspired polygonal skeleton structure for vibration isolation: Design, modelling, and experiment

Inspired by the safe landing of a cat falling from a high altitude, a bio-inspired polygonal skeleton (BIPS) structure is proposed, and its nonlinear characteristics are systematically studied to explore its potential application in the suppression of vibration. The polygon is formed by the skeleton structure of the cat’s entire body and the ground. The BIPS system consists of two symmetrical bionic legs with three robs (as skeleton) and four...
