Modeling of wheeled vehicles is one of the main directions of development and practical appli-cation of software systems based on modeling the dynamics of body systems. In this paper, a tech-nique for analyzing a vehicle tire by the finite element method under various types of loading is considered in order to identify the parameters of its simplif...
An algorithm for computer modeling of the processes of wear and accumulation of the rolling contact fatigue (RCF) damage in railway vehicle wheels is introduced. The combined criterion of contact fatigue is obtained on the basis of the specific strain energy and of the criterion theories of strength. The proposed criterion is tested on the Hertzian...
An algorithm for computer modelling of the process of accumulation of rolling contact fatigue (RCF) damage in railway vehicle wheels is introduced. The amplitude of maximum shear stress is adopted as a criterion for fatigue failure during rolling. RCF curves for wheel steels with a hardness 255–330 HB are obtained by processing the results of the R...
