6. Rolling Bearing Vibrations : The Effects of Varying Compliance, Manufacturing Tolerances and Wear
Sammanfattning : .... LÄS MER
7. Evolution of artificial defects during shape rolling
Sammanfattning : Very often defects are present in rolled products. For wire rods, defects are very deleterious since the wire rods are generally used directly in various applications. For this reason, the market nowadays requires wire rods to be completely defect-free. Any wire with defects must be rejected as scrap which is very costly for the production mill. LÄS MER
8. On Rolling Variators, A study of power transmitting rolling variators when changing speed ratio
Sammanfattning : The introduction of the concept Rolling Variators is proposed for rolling contact continuously variable transmission.A theoretical study of rolling variators when changing the speed ratio during power transmission is presented. LÄS MER
9. Truck tyre rolling resistance : Experimental testing and constitutive modelling of tyres
Sammanfattning : Global warming sets a high demand to reduce the CO2 emissions of vehicles. In the European Union heavy-duty road transports account for 6 % of the total greenhouse gases and one of the main factors affecting these emissions is related to the rolling resistance of tyres. LÄS MER
10. Thermal impact on rolling contact fatigue of railway wheels
Sammanfattning : Rolling contact fatigue (RCF) is a very common and costly damage mechanism for rails and wheels. This thesis investigates the influence of combined thermal and mechanical loading on RCF of railway wheels on the basis of numerical predictions. LÄS MER
