Seahorse‐exoskeleton‐inspired structure with linear‐to‐torsion transition property for low-frequency vibration isolation

The square exoskeleton of seahorses can transit linear motion into torsion to dissipate energy and protect the vertebrate when subjected to external disturbances. Inspired by the self-protection mechanism of the linear-to-torsion transition of the square exoskeleton of seahorses, a novel seahorse-exoskeleton-inspired structure (SES) is designed, which consists of two oblique rods and springs, and a rotational disc. The geometric relationship and dynamic model are established to reveal the corresponding nonlinear stiffness, adjustable high carrying capacity and large working range characteristics. The dynamic equation of the SES is derived according to the Lagrange equation and the frequency response…
