  Praca pośwoęcona jest kierunkowości emisji hałasu opon i nawierzchni drogowych. Opony są dominującym źródłem haasu w pojaździe poruszającym się w typowych warunkach ruchu drogowego. Hałas ten nie jest bezkierunkowy jak to przyjmuje się w modelach obliczeniowych hałasu. Takie założenia wynikają z ograniczonej dostępności danych dotyczących kierunkowości i mogą prowadzić do niedokładności przy prognozowaniu hałasu drogowego. Praca...

  - Year 2015

  Reduction of tire/road noise is one of the biggest environmental challenges of road traffic. To reduce that noise it is necessary to perform acoustic measurements on the base of wellproven standard procedures. One method of measurements that is in common use, namely the Close Proximity Method (CPX), is described in standard ISO-DIS 11819-2. As this method is used to classify road surfaces regarding their influence on vehicle noise,...

  During interaction between tire and road surface three very important phenomena are always in effect. One of them (very desirable) is friction that is important for traction, braking and cornering. Two other phenomena are not desirable at all, that is rolling resistance and noise. This paper discusses relations between road surface and tire parameters versus tire rolling resistance. Road surface texture, porosity, impedance, strength...
