Simulation of tyre rolling resistance generated on uneven road

Numerical Computation of Rolling Resistance Based on the Result of Tire/Road Static Contact Analysis

Among various dissipating mechanisms, the viscoelastic effect of rubber material on creation of rolling resistance is responsible for 10-33% dissipation of supplied power at the tire/road interaction surface. So, evaluating this kind of loss is very essential in any analysis concerned with improving the fuel consumption of vehicles and resultantly energy savage. Hysteretic loss is a fraction of...

Three 3-Axis Accelerometers on the Inner Liner of a Tyre for Finding the Tyre-Road Contact Friction Indicators

Direct tyre-road contact friction estimation is essential for future active safety systems. Friction estimation methods were proposed earlier for driving conditions in the presence of a slip angle or slip ratio. However, the estimation of friction from a freely rolling tyre is still an unsolved topic. This study uses three 3-axis accelerometers on the inner liner of a tyre to detect friction po...

Road surface influence on rolling resistance Coastdown measurements for a car and an HGV

Preface On commission of the Swedish Road Administration, VTI has made a study of how road surface properties (primarily macrotexture and unevenness) affect rolling resistance and fuel consumption of vehicles. Contact person at the Road Administration has been Per-Erik Westergren. Project leader at VTI has been Rune Karlsson. Ulf Hammarström has initiated the project and has had the role of gen...
