Limb-inspired bionic quasi-zero stiffness vibration isolator

Vibration reduction has always been one of hot and important topics in mechanical engineering, especially for the special measurement instrument. In this paper, a novel limb-inspired bionic structure is proposed to generate negative stiffness and design a new quasi-zero stiffness isolator via torsion springs, distinguishing from the existing tension spring structures in the literature. The nonlinear mathematical model of the proposed structure...
