In rubber friction studies it is usually assumed that the friction force does not depend on the sliding direction, unless the substrate has anisotropic properties, like a steel surface grinded in one direction. Here we will present experimental results for rubber friction, where we observe a strong asymmetry between forward and backward sliding, where forward and backward refer to the run-in direction of the rubber block. The observed effect could be very important in tire applications, where directional properties of the rubber friction could be induced during braking.

“…of steel or aluminium, most of the material loss can be allocated to the rubber. Within the proposed modelling approach, the volume loss is considered in module 4 by the non-linear spring elements as follows: The spring elements represent a certain rubber volume, and by a reduction in the spring lengths according to a wear law, the wear process is covered 26. However, results from simulations with local wear are not shown within the scope of this paper.…”

This work deals with the experimental investigation and modelling of adhesion and friction of rubber. With the recently developed adhesion test rig, the contact partners can rapidly be separated while the contact force is measured. The results reveal a strong influence of the preload duration and preload level. Furthermore, a modular modelling concept for dynamic systems with rubber components undergoing sliding friction is presented and exemplified by a tyre tread block. The model considers the geometry of the rubber component, the parameter dependent friction, the roughness induced non-linear contact stiffness and the wear effects. The measurements of high frequency, self-excited tread block vibrations are performed on a tribometer test rig and compared to corresponding simulations with the proposed model.

The dynamic behaviour of a tyre tread block is described by a modularly arranged model. Special emphasis is laid on the influence of the force-displacement characteristic between rubber and the rough surface. In the simulation the rough surface on which the tread block slides is modelled as smooth with the friction characteristic of the respective material pairing and a non-linear description of the local tyre/road interaction. This leads to an adequate description of the contact partners without losing numerical efficiency. Furthermore the model considers wear that changes the block geometry and thus the vibrational behaviour. With the presented model of a tyre tread block dynamic effects like friction induced vibrations are simulated. Effect of non-linear contact stiffness and wearAt the beginning of the sliding process the local contact pressure shows a distinct maximum at the run-in edge. It levels out due to wear until a constant pressure distribution is reached. The block shape changes from rectangular to a typical s-shape,
