Analysis of Data and Examination of Worn Pads from TECOM T-142 Track Pad Test

Abstract:

Nineteen rubber compounds were tested in T142 tank tracks pads at the Yuma Proving Ground TECOM Test 1-VC-087-142-027. The wear data were analyzed with the objective of selecting some of these compounds for use in a projected study of the correlation between field wear and wear on a test machine which is currently being constructed. Recommendations are made based on these data. Some of the worn pads were sent to MTL and were examined visually and photographed. An abrasion pattern i.e., a series of parallel ridges was found on most of the pads which had been worn on the paved road course. Some of these patterns were examined in more detail by microscopy and profilometry. Some of the pads worn on the paved road developed long horizontal slits or pockets. On the hilly cross- country and combination courses, failure was primarily by chunking, though some pattern abrasion was also detected in a few pads.
