Abstract The negative stiffness exhibited by bi-stable mechanisms together with the tunable superelasticity offered shape memory alloy (SMA) wires can enhance dynamic resilience of a structure in context vibration isolation. effects and superelastic damping base-isolated structures are here explored carrying out an extensive study nonlinear response via pathfollowing, bifurcation analysis, time...

Engine is the main source of vibration that generates unwanted noise and vehicle chassis. Especially, in submarine applications, radiation signatures can be detected at some distance away from using a sonar array. Thus quiet operation crucial for submarine’s survivability. This study addresses reduction force transmissibility originating engines transmitted to hull through engine mounts. An ine...
