| Abstract: | A mathematical model was developed for a complex nonlinear coupling isolator for attenuating vi- bration which coupled quadratic damping, viscous damping, Coulomb damping, and nonlinear spring forces. The approximate analytical solution for the dynamic transmissibility of the isolator was deduced by combin- ing Fourier transforms and the harmonic balance method with deterministic excitation. The mathematical characteristics of the dynamic transmissibility were analyzed to illustrate the dynamic performance of the isolator. The analytical results show multiple solutions, especially the low-frequency attenuation characteris- tics below the resonance frequency. The results provide a theoretical basis for the design of nonlinear isolators. |
