Abstract: | This study is concerned with the analysis and design of the force and displacement transmissibility of nonlinear viscous damper
based vibration isolation systems. Analytical algorithms are derived using the Ritz–Galerkin method to evaluate the transmissibility
of SDOF displacement vibration isolation and force vibration isolation systems where a nonlinear viscous damper is used as
an energy dissipating device. The results reveal that compared to linear dampers, nonlinear viscous dampers can more significantly
improve the system vibration isolation performance in a wider frequency range. A procedure is then proposed based on the analysis
results to facilitate the design of nonlinear viscous dampers for system vibration isolation purposes. These results have
significant implications for the design of vibration isolation systems in many engineering applications. |
