3 DOF Lumped Mass Tracked Vehicle Model

Abstract:

A 3 DOF lumped mass tracked vehicle model was constructed in Matlab Simulink Environment and used for positioning the vehicle on gradients and missile firing operations. Pitch center, roll center and system parameters such as equivalent stiffness values, equivalent damping values and equivalent mass/inertias of 3 DOF model were obtained from 32+ degrees of freedom tracked vehicle model by simulations. Moments in pitch and roll directions were applied to the vehicle to find the pitch and roll centers. A range of step forces in bounce direction and a range of step moments in pitch and roll directions were applied to the vehicle and responses in the related directions of 32+ degrees of freedom model were used to determine the system parameters of 3-DOF model. Finally attitude of the vehicle on the gradients and missile firing scenario were simulated with both models and the results showed that 3 DOF model reasonably predicts the behavior of the tracked vehicle.
