Abstract:

A field test program was conducted with four tracked vehicles to determine how strongly the presence of the track affects ride dynamics and to guide in the development of a mathematical model. The vehicles were towed over an assortment of obstacles, first with tracks installed and then with tracks removed. A direct comparison of dynamic responses under these two conditions indicated that the influence of the track is strongly dependent on velocity, and that mathematical models of tracked vehicles must incorporate a track contribution. A mathematical model that portrays essential features of track mechanics without excessive detail was developed.
