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.

尽管橡胶履带车辆的数量不断增加，但没有用于预测和优化此类车辆能源消耗的工程模型。要建立这些模型，需要开发导致橡胶履带系统内部损失的现象模型。本文提供了一个描述橡胶履带横向振动引起的损耗的模型。使用该模型做出的预测是在重型越野车的橡胶样板样本上进行的初步实验测试的背景下进行讨论的。模型预测和实验测试表明，橡胶履带的一阶模态振动引起的损耗相对于橡胶履带系统的总内阻而言是微不足道的。但是，根据模型预测，由于与高阶模态相对应的高振幅轨道振动，预计橡胶履带式底盘内阻会显着增加。为了使该模型在实践中适用，演示了一种确定模型基本参数的方法，包括弯曲刚度和振动阻尼的减小量。通过计算证实了该方法的准确性，其中预测了样本轨迹的下垂和第一模式自由振动的频率分别具有10％和1.8％的误差。通过这种方法获得的参数值适用于对各种越野车辆进行建模。该方法可以应用于许多其他类型的增强橡胶带，例如传送带。
