In the pres.nt s.udy, the Volterra s.ries.theory is.adopted to theoretically inves.igate the force trans.is.ibility of multiple degrees.of freedom （MDOF） s.ructures. in which an is.lator with nonlinear anti-s.mmetric vis.ous.damping is.as.embled. The res.lts.reveal that the anti-s.mmetric nonlinear vis.ous.damping can s.gnificantly reduce the force trans. mis.ibility over all res.nance regions.for MDOF s.ructures.with little effect on the trans.is.ibility over non-res.nant and is.lation regions. The res.lts.indicate that the vibration is.lators.with an anti-s.mmetric damping characteris.ic have great potential to s.lve the dilemma occurring in the des.gn of linear vis.ous.y damped vibration is.lators.where an increas. of the damping level reduces.the force trans.is.ibility over res.nant frequencies.but increas.s.the trans.is.ibility over non-res.nant frequency regions. This.work is.an extens.on of a previous.s.udy in which MDOF s.ructures.ins.alled on the mount through an is.lator with cubic nonlinear damping are cons.dered. The theoretical analys.s.res.lts.are als. verified by s.mulation s.udies.
