“…The flexible ring tire model was first introduced by Tielking (1965) and Klingbeil (1980), who made a significant initial contribution. Additionally, Captain et al (1979) developed four tire models (the point contact tire model, the rigid tread band tire model, the fixed footprint tire model, and the adaptive footprint tire model) and compared them with a six degree-of-freedom nonlinear simulation of a cargo truck to evaluate dynamic performance.…”

A lumped tire model was developed with consideration of the enveloping property in order to predict the natural tire frequency. Tire stiffness was classified into vertical, sidewall, and enveloping stiffnesses, and the tire characteristics were analyzed in detail experimentally and via finite element analysis. In addition, the effective masses of the tire tread and belt were extracted directly from design specifications taking into account the sizes and material properties of different rubber blocks. Using the design parameters of the tires, natural frequencies were calculated from the derived model and were compared with experimental results. Finally, based on good agreement with experimental results, sensitivity analysis was performed to verify the effect of tire stiffnesses on the natural frequencies.

“…Klingbeil [5] and Klingbeil et al [6] developed a viscoelastic model for rolling resistance calculations where rolling losses were associated with seven deformation mechanisms in the tyre structure. These rolling losses were computed through harmonic analyses of all deformation cycles and the application of a loss tangent factor to the maximum stored strain energy for each spectral component.…”

The paper deals with tyre modelling to predict the rolling resistance of truck tyres under a dynamic vertical load. A model originating from Pacejka is applied and modified to perform the necessary calculations. The predictions are compared with the available experimental data on rolling resistance under dynamic vertical load given by Popov et al. The analysis is extended into a larger frequency range so that other models can be also discussed and compared. Within the frequency range considered and based on the experimental data, Pacejka's model appears to give the best results.
