| Summary: | The main goal of the study is investigation of the effect of an interference fit between the wheel hub and the axle of a rail vehicle as well as some axle dimensions on the state of stress in the transition zone in vicinity of the connection: hub wheel - axle journal. An important role in behaviour of the fatigue notch occurring there plays the interference fit. The influence on the quantitative effects of the stress-strain state is to be considered. In order to investigate this phenomenon the finite element method with use of the three-dimensional elements and the contact was applied. The problem is important because of the increasing speed of modern passenger vehicles. Additionally, a threat occurs not only because of the loss of capacity of the axle, but also because of the possibility of slip between the wheel and the axle journal. |
