“…However, since creepage is generally dependent on the dynamics of the rolling system, i.e. that it changes during dynamic rolling, this situation can lead to very complex dynamics as presented in ref [13].…”

In this age of virtual design, high-performance machines, and precise motion control, the abilityto characterize friction and wear processes and then to model and simulate them, becomes a pertinentissue. This communication gives a condensed overview of the generic characteristics of friction, thereafter,generic models, developed at KULeuven, PMA, are presented and discussed.with Leuven Air Bearings N.V. since Sept. 2010In regard to friction, both sliding and rolling are considered. The characterization concerns (i) therelationship between the friction (traction) force and the state of sliding of the system (displacement,velocity,…), at a given normal load; (ii) the relationship between the coefficient of friction and the normalload.As regards frictional behaviour in function of sliding (rolling) state, the main features are: (i) pre-sliding (prerolling) hysteresis and (ii) gross-sliding (rolling) dynamics. Models are presented that capture those featuresand relate them to the contact characteristics. Comparison with experimental results is also presented forthe main features. Secondly, the dependence of the coefficient of friction on the normal load is identifiedand modelled.Finally, regarding wear simulation, the generic friction model is extended to cater for an asperity populationthat changes during the lifetime of sliding. Based on fatigue considerations, asperities get broken after acertain number of contact cycles, and are replaced by smaller ones. With the aid of this model, we try tocorrelate energy dissipation with wear evolution, and support that by experimental observation.

“…Modelling and numerical simulation of mechanical systems with frictional contacts in their general case require discretization of the deformable contacting bodies near the contact zone or at least discretization of the contact surface [1][2][3]. For the rolling contact one can use the well-known CONTACT software [2].…”

In the work there is presented a mathematical model of a rattleback lying on a horizontal plane, with special attention paid to modelling of the contact forces. Friction force modelling concerns a certain class of problems, where it is possible to assume fully developed sliding on the contact zone. The models are based on the integral expressions assuming the classical Coulomb friction law valid at each point of the contact. In order to obtain a higher simulation speed, a special class of approximations if integral functions is used, being some kind of generalization of Padé expansion. The rolling resistance is modelled as a result of special distortion of contact pressure distribution and takes into account the rolling direction and the elliptic shape of the contact. The work uses previous results of the authors, but more attention is paid to the rolling resistance model, which is extended and analysed in more detail. The models are validated experimentally and their various elements are tested.

“…[3]) or deep analyses of the contact between the system and the surface (see e.g. [4]), have a global character. Then these methods, for their very nature, can determine only a reactive force system equivalent to the real one but, in the general case, these methods cannot determine the single reactive forces in the contact points.…”

We illustrate a theoretical procedure determining necessary conditions for which simultaneous pure rolling kinetic constraints acting on a mechanical system can be fulfilled. We also analyze the sufficiency of these conditions by generalizing to this case a well known and usually accepted assumption on the behavior of pure rolling constraint. We present in detail the application of the procedure to some significative mechanical systems.
