The response analysis of several nonlinear isolation systems subjected to random excitation
The nonlinear isolation system is popular in modern isolation mounting. By using the Fokker-Planck equation and the statistical linearization method and under the condition of random excitation the best damping selection of the dashpots of the stiffening nonlinear stiffness, the response characteristics of the single-degree-of-freedom isolation system of non-antisymmetrical and nonlinear stiffness, and the response analysis of two-degree-of-freedom nonlinear isolation systems are discussed. The selection of some parameters of the nonlinear isolation system is also dealt with by virtue of calculation examples.
