Rolling Resistance Coefficient of Tires
Hasala, Matěj ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
This bachelor thesis focuses on the rolling resistance coefficient of tyres both in terms of the factors that influence this coefficient and in terms of experimental methods for its determination. In the first part of the thesis, the key factors affecting the rolling resistance coefficient are discussed in detail. This is followed by a description of the methods used to measure rolling resistance in laboratory and real-world conditions. The thesis continues with an overview of typical rolling resistance coefficient values for tyres of different categories, which have been further divided into subcategories and compared with each other. The last part of the thesis is devoted to the principal design of a measuring device for rolling resistance measurement. The design takes the cost and capability of obtaining a certificate of roadworthiness into account. Specific measuring instruments and components needed for the homologation process were selected and price calculation of known parts was made.
