Design and Prepared of a New Rubber Composite for Absorption of Vibration in Electrical Generator

Abstract

various vibration materials are available as structure use in equipment insulation. Rubber mounting type is a wide use as machine damping material in electrical generator . Rubber mounting characteristic are improved with thermoplastic addition. In the present paper an investigation of LDPE percentage on the different types of rubber matrix (IIR, SBR/Reclaim) to prepare the composite mounting and comparison these mountings with the prepared blend (SBR:NR)mountings. The works is achieved by using TM16 universal vibration apparatus with modifying the viscous damper into rubber damper and Wallace R-2 Dunlop Triposometer. The results show, increasing the damping ratio () and logarithmic Decrement () with increasing of LDPE percentage of (0-10) (pphr.), and decreasing of decrement of trasmissiblly ratio( T) ,also show reducing of these criteria (,) above 10 (pphr),also can be concluded the best damping characteristics are founded in the SBR/Reclaim with 10% of LDPE type.
