“…Persson's theory, on the other hand, in the latest forms (Lorenz et al [8]), seems to have a surprisingly simple criterion for truncation wavenumber q 1 = 2π/λ min : it is defined where the rms slope reaches H rms (q 1 ) = 1.3 (1) although other authors (Carbone & Putignano [9]) are more cautious about many possible choices to the truncation cutoff, e.g., small dirt particles or rubber wear particles. However, more recently, both Klüppel and co-authors [10][11][12] and Persson and Volokitin [13] seem to attribute a lot more importance to the adhesive term than the viscoelastic one. For example, Lang & Klüppel [12], has an adhesion contribution attributed to peeling effects at the edges which depends on velocity and viscoelastic properties in the simplified form…”

Since the early study by Grosch in 1963 it has been known that rubber friction shows generally two maxima with respect to speed-the first one attributed to adhesion, and another at higher velocities attributed to viscoelastic losses. The theory of Klüppel and Heinrich and that of Persson suggests that viscoelastic losses crucially depend on the "multiscale" aspect of roughness and in particular on truncation at fine scales. In this study, we comment a little on both theories, giving some examples using Persson's theory on the uncertainties involved in the truncation of the roughness spectrum. It is shown how different choices of Persson's model parameters, for example the high-frequency cutoff, equally fit experimental data on viscoelastic friction, hence it is unclear how to rigorously separate the adhesive and the viscoelastic contributions from experiments.

“…In addition, the static frictions of rubber-steel and PMMA contacts are plotted in Figure 8, either. As being proportion to the real contact area, the increasing trends of the static frictions show good agreement with that of the real contact areas [7,27]. There are two major soft contact models to predict the level of friction.…”

“…Tribological behaviors of rubber in soft contact is of paramount importance and have been widely investigated in many fields. It is well known that the friction force is related to the total area of real contact [6], and friction of rubber-steel contact is proportional to normal load, due to the increase in real contact zone [7]. Adhesion force is seen as a very important factor affecting rubber friction in certain contact conditions, because the molecular interaction forces within and around the contact area add the effect of the normal load.…”

The Static Frictional Behaviors of Rubber for Pipe-Laying Operation

Featured Application: This research aims to reveal the static frictional behavior of rubber pipe contact systems during a pipe-laying operation. The testing results of friction facilitate the selection of appropriate contact pairs for tribological optimal design of the tensioner. The discussion about the instability of static friction is helping us to avoid pipe slipping accidents and to maintain accuracy of pipeline installations.Abstract: Experimental research is carried out to reveal the static frictional behaviors of rubber pipe contact systems. This research is motivated by deep water pipe-laying operations where rubber blocks are used to clamp the pipe to supply sufficient static friction. Within this context, a friction testing instrument has been designed to mimic a situation of the beginning of the pipe-laying installation. Using this instrument, the maximum static friction forces (F) of a rubber pipe contact system are tested. The results show that the ultimate values of the static frictions fluctuate due to the increasing rate of the tangential load (F T ). The evolution of contact between rubber and polymethyl methacrylate (PMMA) pipe is observed to identify the formation and propagation of the folds within the apparent contact area. In addition, it is confirmed that the evolution of contact is influenced by the folds and creep of the rubber surface. The creep deformation takes primary effect in accelerating the separation of the interfaces of contact during relative high normal loads (20, 30, 40 N) and low increasing rate of F T ; whereas for all of the testing normal loads (10-40 N), the propagation of the folds release the energy which is stored in the interface of rubber when the increasing rate of F T is high. Therefore, the fluctuation of the maximum static friction of the contact system can be regarded as a consequence of interaction of the creep and folds. Furthermore, the instability of the coefficient of static friction in this test has been examined, and it indicated that the creep and folds could affect the static friction distinctly within a certain range of a normal load. This research is beneficial for arranging appropriate normal loads and laying speeds to avoid pipes slipping during a pipe-laying operation.

This study is devoted to experimental research of rubber friction in sliding contact with rough surface. Influence of pressure, bulk temperature and sliding velocity on friction coefficient in dry conditions is analysed for two rubber compounds with different viscoelastic properties. Grosch method of master curves construction is used for analysing of friction measurements. Such analysis is performed for different temperatures and velocities at constant normal load. The obtained friction master curves are combined into a single friction map. The friction maps demonstrate the influence of viscoelastic properties of rubber on friction coefficient in dry rough contact. Also friction maps show the influence of adhesion and hysteresis contributions into friction coefficient for different rubber compounds.
