Estimation of the Fatigue Lifetime of Metal Rubber Isolator with Dry Friction Damping

Abstract:

Article Preview

Metal rubber (MR) sleeve isolators have been widely applied in aerospace industry. An experimental investigation into its fatigue lifetime was conducted. The results indicate that its performance is determined by the following factors: the relative deformation of MR sleeve elements, the preloading of sleeve elements, friction coefficient of metal wires and vibration amplitude. It is concluded that solid lubricates can increase the lifetime of MR isolator greatly but lower its ability to dissipate vibrating energy.
