Based on the idea of bionics, innovation and optimization of vibration isolation model by imitating the structural characteristics of biological system is a hot issue in the field of vibration isolation. This review systematically classifies the existing bio-inspired isolators according to the different inspiration sources of bionic design. It also elaborates and compares the restoring force constitutive and vibration isolation performance of bio-inspired isolators with different design principles in detail. The aim is to clarify the influence of geometric configuration and adjustable parameters through the transverse comparison of the vibration isolation band of the bioinspired isolator, so as to clarify the relationship between the geometric design of the isolator and vibration isolation performance. In addition, the future development prospect and research direction of bioinspired isolators are prospected.
