Design and prepared of a new rubber composite for absorption of vibration in electrical generator

الملخص EN

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 (ξ) and logarithmic Decrement (Δ) with increasing of LDPE percentage of (0-10) (pphr), and decreasing of decrement of trasmissiblly ratio (T) ,also show reducing of these criteria (ξ ,Δ) above 10 (pphr),also can be concluded the best damping characteristics are founded in the SBR / Reclaim with 10 % of LDPE type.
