“…In order to fulfil the contact geometry, contact forces are needed which ensure the required deformations of the tyre. The model used here is based on the convolution approach originally developed for tyres by one of the authors [21], and its subsequent enhancements by several authors [35][36][37]. Only contact deformations and forces in normal direction are considered.…”

“…As is shown in Fig. 3(b), contact springs can instead be introduced between the possible points of contact on the tyre and the road to account for the difference in stiffness [36].…”

“…In contrast to the model described in [36], only linear contact springs are used here. This is motivated by the fact that the resolution of the available road roughness data is not sufficient 1 for a proper estimation of the nonlinear stiffnesses as outlined in [36].…”

a b s t r a c tThe reduction of rolling resistance is essential for a more environmentally friendly road transportation sector. Both tyre and road design can be utilised to reduce rolling resistance.In both cases a reliable simulation tool is needed which is able to quantify the influence of design parameters on the rolling resistance of a tyre rolling on a specific road surface. In this work a previously developed tyre/road interaction model is extended to account for different tread patterns and for losses due to small-scale tread deformation. Calculated contact forces and tyre vibrations for tyre/road interaction under steady-state rolling are used to predict rolling losses in the tyre. Rolling resistance is calculated for a series of different tyre/road combinations. Results are compared with rolling resistance measurements. The agreement between simulations and measurements is generally very good. It is found that both the tyre structure and small-scale tread deformations contribute to the rolling losses. The small-scale contribution depends mainly on the road roughness profile. The mean profile depth of the road surface is identified to correlate very well with the rolling resistance. Additional calculations are performed for non-traditional rubberised road surfaces, however, with mixed results. This possibly indicates the existence of additional loss mechanisms for these surfaces.

Abstract. By collecting different grade road images, standard sample library was established. Using fuzzy approach degree algorithm, the approach degree of reconstructed road surface and criterion of road was determined. Then power spectrum of road roughness was built. According to the parameters of power spectrum, we can obtain a 3d figure of road surface by improved harmonic superposition method.

In reality, it is found that most practical structures do not comply with the assumption of linearity [5,[9][10][11][12][13]. The metal-plastic traveling joints may introduce nonlinearity in the large machine structure.…”

In order to select the best possible design from various candidates based on structure configurations of traveling components, it is essential to evaluate the effects of traveling joints on dynamic behavior of large machine tools. Firstly, regression analysis and energy method were used to determine the nonlinear parameters of the metal-plastic joints. Then, a nonlinear receptance coupling approach was used to establish a simplified model of a large machine tool including nonlinear joints. The evaluations of the large machine tool were analyzed with different milling forces. The results show that the nonlinearity of traveling joints significantly influences the resonant frequency and the response amplitudes. Experimental verifications were performed on a prototype of a large machine tool for milling large gears.
