1. Optimization of truck tyres selection
Sammanfattning : This thesis, which consists of an introduction and five appended papers, concerns the optimal selection of tyres for a variety of vehicle configurations as well as operating environments. The selection problem stems from a project cooperation between Chalmers University of Technology and Volvo Group Trucks Technology. LÄS MER
2. The simulation of car and truck tyre vibrations, rolling resistance and rolling noise
Sammanfattning : The road transportation sector places a severe burden on the environment in the form of CO2 emissions and road traffic noise. Both of these environmental prob- lems can be related to car and truck tyres. LÄS MER
3. Passenger Car Wheel Aerodynamics
Sammanfattning : Current and future requirements for efficiency force the automotive industry to consider all aspects of reducing the energy consumption of road going vehicles. An important aspect of reducing fuel consumption is reduced aerodynamic drag, which at highway cruising speeds is dominating the total drag force for both cars and heavy goods vehicles. LÄS MER
4. Power dissipation in car tyres
Sammanfattning : Traffic is a major source of green house gases. The transport field stands for 32 % of the energy consumption and 28 % of the total CO2 emissions, where road transports alone causes 84 % of these figures. LÄS MER
5. On Tyre Rotation Modelling and Cooling Flow Measurements
Sammanfattning : With the technological computer advancements, vehicle development is relying more and more on simulations as an alternative to testing. A similar trend follows in aerodynamic development of vehicles where Computational Fluid Dynamics(CFD) simulations are increasing in complexity and accuracy. LÄS MER
