Evaluation of the accuracy of the rigid body approach in the prediction of the dynamic stresses of complex multibody systems

摘要

In this paper, the floating frame of reference and absolute nodal coordinate formulations (ANCF) are explained in detail and used in the stress analysis of the track links in a complex three-dimensional tracked vehicle model. One of the most common areas of failure for such tracked vehicles is attributed to the failure of the track link chains, and therefore, performing a detailed fully coupled stress analysis, as the one described in this investigation, is necessary in order to obtain more accurate stress results and avoid failure of such complex vehicle systems.
