Abstract
Track links for high mobility tracked vehicles usually consist of track shoe bodies, track pins, rubber pads, end-connectors, and rubber bushings. Since the track pin is subjected to large transverse track tension from the track link, conventional track pins for high mobility vehicles are usually made of high strength steel, such as forged chrome-molybdenum steel, which increases the weight of tracked vehicles due to the high density of steel. Weight reduction has been the principal goal of many of the experimental track programs since World War II. However, great weight reduction in the track pin has not been achieved for several decades except a few experimental works. Therefore, in this paper, the axiomatic design approach was employed to design a lower weight track pin with composite materials. From the design of composite track pin, the weight reduction of 50% as well as better endurance life was achieved.
