Analysis of Armoured Vehicle Track Loads and Stresses, with Considerations on Alternative Track Materials

Abstract

This report sets out the basis for calculating the loads applied to the track of an armoured-vehicle in service conditions. The analysis includes the effects of normal traction, inertia forces from rotation of the individual shoes, friction, and vibration. It also includes a basic analysis of forces induced when the vehicle turns and negotiates obstacles. The report looks in some detail at the tracks of the M113 vehicle, and provides an estimate of the loads and load cycles applicable to this configuration. A stress analysis of the three components of the track (shoes, rubber bushes, and pins) is included. Consideration is given to the replacement of the existing track shoes with ones made from an aluminum alloy/SiC metal matrix composite. The report includes a summary of the effects to be tested and the property requirements to be met if such a replacement were to be tried.
