Modification and Evaluation of Elastomer Test Machine (ETM)

Abstract

The Elastomer Test Machine (ETM) which was constructed in May 1988 has been modified to include synchronization of the linear table with the 'Ram Action' of the press, a new linear Model 2, measurement of the horizontal force of the sample and a sip ring system for the measurement and control of temperature. The Elastomer samples can now be tested at different temperatures (>140 C) in the stationary impact mode, in two linear abrasion mode and in a rotational mode (and combinations thereof). Temporal qualitative data on load and displacement can be recorded which may provide a qualitative analysis of the elastomer degradation process. A comprehensive set of test data were obtained with the ETM using all the modes for 57 different elastomer samples, provided by the US Army (51 samples) and the US Navy (6 samples). The ETM tests provide a performance analysis of any track pad elastomer material and may predict a projected service life.
