摘要：
Here, starting from lumped parametric model of hydraulic damping rubber isolators, their unified complex stiffness linear model was derived and analyzed. Based on the derived linear model, simultaneously considering the nonlinearity of the inertia channel damping of hydraulic damping rubber isolators and the nonlinearity of upper liquid chamber stiffness, a new nonlinear model was established. This model could reflect amplitude and frequency correlation of dynamic characteristics of hydraulic damping rubber isolators. Finally, under simple harmonic and random excitations, the nonlinear model established here was used to analyze dynamic responses of hydraulic damping rubber isolator, and the results with test results were analyzed contrastively. © 2023 Chinese Vibration Engineering Society.
