Abstract Experimental and analytical investigations were made to find the rebound characteristics and temperature rise in elastomer slabs subjected to repetitive impact. For its mechanical response, the elastomer was modeled as a linearly viscoelastic material, and its frequency and temperature dependent moduli were determined by Rheo-vibron tests. The experimental traces of impact force vs. time were studied in relation to various input parameters (e.g., impact velocity and slab thickness). An iterative method was devised to calculate the pulse from the input parameters enabling the analyst to estimate the peak force or duration of impacts occurring in a specific damper. As opposed to single (isolated) impacts, the repetitive impact process is conducive to temperature rise in the elastomer slabs resulting in a steady state temperature distribution. Under various input parameters, the temperature on the surface and inside the rubber was measured in the steady state. Both a simplified and a pulsed-heat-generative mathematical model was used to analytically estimate these temperatures.
