11. Excitation of Tyre Vibrations due to Tyre/Road Interaction
Sammanfattning : Tyre/road noise is the main contributor to road traffic noise at speeds above 40 km/h for passenger cars and above 70 km/h for heavy trucks. Research has been carried out during the last thirty years in order to understand and quantify the generation mechanisms responsible for tyre/road noise. LÄS MER
12. Modelling of Dynamic Contact - Exemplified on the Tyre/Road Interaction
Sammanfattning : Noise is a severe problem in modern society. Road traffic noise is a substantial contributor and the tyre/road interaction is the main noise source for normal driving conditions. Despite more than 30 years of research, there is a lack of quantitative tyre/road noise prediction models. LÄS MER
13. Models of porous, elastic and rigid materials in moving fluids
Sammanfattning : Tails, fins, scales, and surface coatings are used by organisms for various tasks, including locomotion. Since millions of years of evolution have passed, we expect that the design of surface structures is optimal for the tasks of the organism. These structures serve as an inspiration in this thesis to identify new mechanisms for flow control. LÄS MER
14. Analysis of elastic waves in rods from two-point strain measurement : extension tin non-uniform systems and applications to bit-rock interaction and rotational mobility
Sammanfattning : .... LÄS MER
15. Modelling of wheel/rail interaction considering roughness and discrete irregularities
Sammanfattning : The interaction between wheel and rail is the predominant source of noise emission from railway operations in a wide range of conventional speeds. On the one hand, this wheel/rail noise concerns rolling noise and impact noise caused by the vertical interaction excited by roughness and discrete irregularities of the wheel/rail running surfaces, respectively.
