Prediction of Wear Resistance of Rubber Track-Pads by Standard Laboratory Tests.
Abstract
Various laboratory tests were investigated to determine if such tests could be used in predicting the wear resistance of rubber track pads. The main causes of track pad failure in service tests performed over the past 17 years were found to be chunking, cutting and abrasion. These service-induced failures were believed to be caused by poor tear strength (especially at elevated temperatures), poor resistance to crack growth, and poor abrasion resistance. Correlation was sought between service wear ratings and the results of standard tests for tear strength, resistance to crack growth, and abrasion resistance. Correlation was found, but only when the results of all three laboratory tests were compared with service test data. These tests will be useful in predicting the service life of pads fabricated from experimental elastomeric compositions, thus the need for costly and time-consuming service tests in the field will be minimized.
