Nonlinear Dynamics of Tracked Vehicles

Abstract

The objective of this research project to develop nonlinear multibody computer methodologies that take into account the effect of the three dimensional interaction between the track chains and other vehicle components such as the sprockets, idlers, and the rollers as well as the effect of the dynamic coupling between the rigid body displacements and the elastic deformation of the vehicle components. In the methods developed in this research project, the kinematic degrees of freedom of the track chains are taken into consideration when the dynamic equations of the vehicle are formulated. It is demonstrated that significant reduction in the number of degrees of freedom of the track chains can lead to an inaccurate modeling of the vehicle dynamics and also to numerical difficulties in the computer simulation of this type of vehicles. Therefore, in this research project detailed three dimensional tracked vehicle models that take into account the effect of the chain degrees of freedom are developed.
