Models for ultra-high damping natural rubber (UHDNR) a new material for structural dampers are investigated. Experimental tests of structural dampers made from UHDNR and the observed mechanical properties are summarised. Two load rate independent hysteresis models which are more accurate for UHDNR than existing hysteresis models are proposed. Good agreement is observed between the experimental results and (he models.

Abstract

Models for ultra-high damping natural rubber (UHDNR) a new material for structural dampers are investigated. Experimental tests of structural dampers made from UHDNR and the observed mechanical properties are summarised. Two load rate independent hysteresis models which are more accurate for UHDNR than existing hysteresis models are proposed. Good agreement is observed between the experimental results and (he models. The more complex of the two models the sequential asymptote model represents accurately the behaviour of UHDNR under the random load histories that are anticipated for structural dampers.
