Abstract

A bio-inspired ceil-like structure which can be considered as a pentagon-shaped structure is investigated for understanding and exploring its nonlinearity to achieve vibration isolation in multi-direction. Firstly, the model of low dynamic and high static vibration isolator is established, and the relevant system parameters are designed based on the equations of equivalent restoring force and stiffness of the system. Then the dynamic equations of the system are deduced and established. The natural frequencies of configurations with different connections of spring are studied and the dynamic response harmonic base excitation is derived. And finally, the isolation performance is evaluated by deducing the displacement transmissibility of the system. Several configurations of the pentagon shaped structure are designed for different working environments. The analysis shows that the structure can present flexible stiffness and have good vibration isolation characteristics in both vertical and horizontal directions. The result will provide a novel bio-inspired solution which can potentially be employed in different engineering practices for much better vibration isolation and control for multi-direction vibration isolation.
