摘      要：Inspired that the neck structure can stabilize the head from body movements and external dynamic vibration by the role of intervertebral disc and surrounding muscles,a novel multi-layer structure with nonlinear elastic components is proposed in this *** proposed structure is expected for loading the weight of the end effector and isolating bending vibration with lowfrequency in the range of 0.1 Hz to 1 ***,considering the loading,the potential energy,restoring force,and structural configuration in axial direction are ***,the dynamical restoring force and stiffness for bending are modelled for different structural parameters and configurations after the axial *** to the functions of the proposed structure required in applications including loading capacity and bending vibration isolation effectiveness,design criteria are carried *** to the realization of high-order quasi-zero stiffness property,the effective isolation band for bending vibration can be extended from about 0.08 *** addition,based on the proposed design criteria,the constructed multi-layer structure displays remarkable dynamical stabilization effectiveness in ultralow frequency *** proposed structure not only provides the biological explanations for car sickness,nausea,and airsickness of humans,but also solves the bottleneck techniques in bioinspired nonlinear isolation structural design for transverse dynamical stabilization,which has remarkable potential applications in the fields of mechanical arm,sensors in satellite etc.
