Electrical Properties of Tank Pad Rubber: A Feasibility Study
Abstract
The purpose of this work is to investigate the feasibility of electrical measurements for improving the life and reliability of tank track pad rubber. Immediate goals are to determine if electrical measurements can be used to distinguish various types of rubbers used in tank track pads, to obtain more fundamental information about the electrical properties of the rubber, and to make recommendations. The most important results were related to the effects of pressure on resistance, and resistance relaxation. Each of the six different compositions measured had its own resistance increase-relaxation fingerprint. Samples of the same composition had nearly identical fingerprints. A major asset of the pressure-resistance relaxation measurement is that it couples mechanical and electrical properties of the rubber. A correlation between electrical relaxation and certain mechanical parameters such as creep and set recovery was made. The resistance relaxation phenomena can be attributed to various bond breakages and repairs, which can be also be related to mechanical properties.
