“…The range of models begins with the point mass models embedded in the automotive performance simulations that are more focused on powertrain performance (McCullough et al, 2006;Schmid et al, 1998;Xiaoping and Shu, 2002;Rakha et al, 2001), to commercial rigid body dynamics codes that model the individual track blocks and the detailed contact interactions of the running gear elements (Sandu and Freeman, 2005;Slattengren, 2000;Ma and Perkins, 2002). Between these extremes are well-known modelling tools such as the NATO Reference Mobility Model (NRMM) vehicle dynamics (VEHDYN) module and several commercial and custom purpose-driven modelling tools (Priddy, 1995).…”

The estimation of the vehicle acceleration performance plays an important role in the assessment of the vehicle mobility. The estimation becomes difficult in the case of tracked vehicles owing to the complexity of their power pack (consisting mainly of the engine and the hydromechanical transmission) and also because of the tracked running gear. Because of that, this case was taken into investigation and an algorithm was proposed. The algorithm is focused on the estimation of the acceleration performances. The accuracy of the proposed algorithm is compared with the experimental data resulted from the testing of a 50 tonnes tracked vehicle running up to 60 km/h, concluding that the model-based data are in good agreement with the experimental results.
