FE 08.0262 / 2019 / OGB Investigation of a novel Grinding process for the production of completely defined textures.

Use a new grinding processet for the first time a cutting blade that cuts both the grooves and the web surfaces in a controlled manner. Due to this technical development it is possible to produce a homogeneous bridge height during the production. In addition, this method can theoretically achieve an ideal shape for the grinding geometry (rectangular or trapezoidal with a micro-rough surface). It will eIt is expected that the special design of the diamond segments means that the center distances of the webs can be reduced and the contact surfaces between the tire and the road surface can be significantly increased. This should lead to a better distribution of the contact forces as a whole and to a reduction in the local forces in the tire-road contact. As a result, less ripenessen-Fahrbahn-Noise to be expected.

The focus of the research project is on the further development of the grinding technology (texture grinding 2.0) and the grinding textures that can be produced with new cutting tools. The primary goal is for long-lasting surface textures (type S, type S, type A and type A) a high durability of the relevant functional propertiesn To achieve grip and drainage in connection with the acoustic properties, taking into account the stresses that arise (traffic, climate). Another focus of research in this research project is the influence of the sectional image on the relevant surface properties (grip, drainage, noise reduction). In particular, the targeted texturing ofn Grinding and grooving bars for the production of performance-oriented surfaces is of particular interest.

In a multi-stage procedure, different textures are first to be examined in the laboratory for their durability. On the basis of the knowledge gained from the laboratory tests, a demonstrator with different texture variants is then to be produced and measuredch to accompany. With the aid of drill cores, the real textures in the laboratory are to be examined again for their durability. In addition, a texture of the traffic load has to be simulated on the demonstrator so that the surface performance can be measured and analyzed again. In the laboratory as well as on the demonstrator, the analysis ofChanging the surface textures over time plays an important role. A prognosis regarding the durability of the texture geometry and the performance properties of the texture variants used can be derived from the knowledge gained.

The conditions of participation apply to the application for the research order.
