“…According to Wang et al [38], transverse track vibrations adversely affect the energy consumption of tracked vehicles. Although no explicit evidence for this hypothesis is presented by Wang et al [38], it can be explained as follows. The shape of a track subjected to transverse vibrations periodically changes, resulting in the losses attributed to the sliding friction in dry and lubricated pin joints or the mechanical hysteresis of rubber belts or rubber-bushed pin joints.…”

“…The concern regarding high computational complexity of the multibody models of rubber tracks is also raised by Scholar and Perkins [31] and Wang et al [38]. They do not discuss this issue in much detail; however, they introduce an alternative approach in tracks modeling, called the continuum approach.…”

“…Although Wang et al [38] adopt a beam model to describe dynamic behavior of flexible tracks, the assumptions made by Wang et al are quite similar to those of Scholar and Perkins [31]. In Wang et al [38], bending and axial stiffness of a track are assumed to be constant values, whereas damping properties of the track are neglected. In spite of those simplifications, the model by Wang et al predicted the natural frequencies of the first, the second, the third, and the fourth mode of a sample flexible rubber-bushed link track with an error of 2%, 3%, 11%, and 6%, respectively.…”

In spite of an increasing number of rubber-tracked vehicles, there are no engineering models for predicting and optimizing the energy consumption of vehicles of this type. To formulate those models, the models of the phenomena resulting in the internal losses of rubber-track systems need to be developed. This article presents a model describing the losses caused by the transverse vibrations of rubber tracks. The predictions made using the model are discussed against the background of the preliminary experimental tests on a sample rubber track for heavy off-road vehicles. The model predictions and the experimental tests suggest that the losses caused by the 1st mode vibration of rubber tracks are marginal in relation to the total internal resistance of rubber-track systems. However, according to the model predictions, a significant increase in the rubber-tracked undercarriage internal resistance is expected as a result of the high-amplitude track vibrations corresponding to the higher-order modes. To make the model applicable in practice, a method for determining the essential parameters of the model, including the bending stiffness and the decrement of oscillation damping, is demonstrated. The accuracy of the method is confirmed by the computations, where the sag and the frequency of the 1st mode free vibration of a sample track are predicted with an error of 10% and 1.8%, respectively. The parameter values obtained by this method are suitable for modeling a wide variety of off-road vehicles. The method can be applied to many other types of reinforced rubber belts, e.g., conveyor belts.

This study focuses on modeling ideal nonuniform standing beams and towers supporting a constant top mass. We also analyze their dynamical stability, as determining the design parameters influencing their shape and stability holds significant value for structural engineering. Initially, we employ a statical mechanics approach to balance the mechanical and gravitational forces. By solving an initial-value problem, we derive the cross-sectional areas of the columns. Our findings reveal that these areas, rather than the shapes, are the primary contributors to the engineering performance of the columns. Additionally, the top mass acts as a multiplying factor for the cross-sectional areas, and the density distribution along the column determines whether the top should be heavier or lighter. Furthermore, we demonstrate that exponential, parabolic, or linear cross-sections with significantly wider base profiles are crucial for accommodating heavier top loads. Moving on to the dynamical analysis, we consider two ideal tower configurations: FC and SC. Numerical and analytical results reveal that higher modes exhibit shorter amplitudes. FC modes necessitate higher design parameters to resist buckling phenomena, whereas SC modes show lower resistance to vibrational deflections. In terms of stability, a heavier top mass enhances the vertical beam’s stability, while towers with parabolic bases are more susceptible to instabilities.
