Simulation and experimental investigation of tire interaction with snow and ice covered pavement

The dissertation investigates the tire interaction with snow and ice covered pavement. The key parameter describing the interaction are forces generated in the contact of the road and tire influencing stability and maneuverability of the vehicle. The values of these forces are strongly dependent on ambient temperature and road pavement condition. An interaction and its influencing factors of passenger car tire with snow and ice covered pavement are analysed in the thesis.

The thesis includes the introduction, four chapters, general conclusions, the list of references, the list of publications of the author on the subject of the thesis and six annexes.

The introduction reveals the investigated problem, importance of the thesis and the object of research and describes the purpose and tasks of the paper, research methodology, scientific novelty, the practical significance of results examined in the paper and defended statements. The introduction ends in presenting the author’s publications on the subject of the defended dissertation, offering the material of made presentations in conferences and defining the structure of the dissertation.

In the first chapter, sources of scientific literature on the subject of the thesis are reviewed. An analysis of tire forces, experimental research on tire force transmission on snow and ice performed by other authors, mathematical models of tire interaction with snow and ice and efficiency of chemical materias used for winter road maintenance are presented.

In the second chapter, the theoretical analysis of tire tread block interaction with snow and ice and melting of these layers are presented.

In chapter three, the methodologies of experimental research and the used equipment are presented.

In the chapter four, the results of the mathematical modeling and experimental research are analyzed. The obtained experimental results are compared to other authors research results.

On the topic of the dissertation, 6 scientific articles were published: one – in scientific journal included in the Clarivate Analytics Web of Science, two – in reviewed scientifical journal, two – in the Clarivate Analytics Proceedings data base publications, one – in the scientific conference material. Three presentations on the subject have been given in conferences at international level.
