Abstract

Based on the lumped parameter model of hydraulic damping rubber isolator, a unified linear model of complex stiffness is deduced and analyzed. Based on the derived linear model, a new nonlinear model is established by considering both the nonlinear damping of inertia channel and the nonlinear stiffness of upper chamber of hydraulic damping rubber isolator. The model can reflect the amplitude and frequency dependence of dynamic characteristics of hydraulic damping rubber isolator. Finally, the nonlinear model is used to analyze the dynamic response of hydraulic damping rubber isolator under harmonic excitation and random excitation, and the experimental results are compared and analyzed.
