Abstract [en]

Elastomers are commonly used to decrease the sound transmission between apartments in timber framed houses. Inprevious studies, different types of connections have been evaluated. However, the frequency dependent dynamic propertiesin different directions of a connection including elastomers are not fully investigated yet. Previous studies have actuallyshown that elastomers cause the vibrations to increase in the direction perpendicular to the applied load within the lowfrequency span. The properties of the elastomers are needed in order to model the dynamic behaviour and thereby be ableto predict sound and vibration transmissions in wooden houses in the future. With known properties, the elastomerconnections can be modelled using springs and dashpots. In this study, dynamic experiments have been made on elastomerstrips half embedded. The test setup has been subjected to various loads using an electromagnetic shaker. The responseshave been measured and evaluated using modal analysis. With different loads, non-linear characteristics of the elastomers’behaviour have been obtained. The elastomers have also been tested quasi-statically, to obtain a load-deflection curve.Finally, the estimated properties of the elastomers have been included in an FE model using springs and the analyticalresults are compared with the experimental results.
