ABSTRACT

The dynamic simulation of multibody tracked vehicles offers engineers a powerful tool with which they may analyze and design. Currently, parts of these complex mechanisms are introduced to multibody algorithms as rigid bodies. Then in a follow-on structural analysis, the loads from the multibody dynamic simulation are input to calculate strains and stresses within the bodies. The present investigation aims to establish appropriate means by which flexible three-dimensional track links, which allow large relative rotation between the elements, can be modeled. This will pave the way towards the incorporation of detailed flexible structural models into a multibody dynamic simulation environment allowing for an integrated solution. In addition, a new formulation for the interaction between the rigid sprocket teeth and flexible chain is presented. Numerical results are introduced to illustrate the effects of flexible links on the dynamics of tracked vehicles.
