Abstract : A comprehensive study of track/track dynamics was undertaken, utilizing analytical, laboratory test, and field test techniques to develop a better understanding of track dynamics and performance. Analytical techniques were developed to predict track vibration modes, chordal action effects, dynamic tension and path, energy dissipation, tension going over obstacles, tension distribution, pin/bushing stresses and deflections, temperature buildup, and end connector tightening effectiveness. Double-pin track for heavy tanks was analyzed with these techniques, and designs for improved track suitable for the XM-1 tank were developed. A laboratory bushing research machine was designed, and a track-mounted telemetry system was built. (Author)
