Abstract. The article deals with detection of reduced stress in a braked railway wheel, based on thermal transient analysis on virtual models, which influence the characteristics of the railway wheels. Structural analysis was performed by means of the ANSYS Multiphysics program system package. Thermal transient analysis deals with detection of temperature fields which are a result of braking by brake block. The applied heat flux represents the heat generated by friction of brake block. It is applied to a quarter model of the wheel to speed up the calculation. This analysis simulates two braking processes with subsequent cooling. Distribution of the equivalent stress was detected in the railway wheel cross section, at selected points. The input parameters were taken from the thermal transient analysis. These equivalent stresses result from thermal load.

Abstract. This paper presents results of selected load cases for the modified freight wagon bogie frame. It comprises of two main parts. The first part is addressed to the introduction of a modified freight wagon bogie. There are described conditions for rail vehicles approval and mainly load cases which every bogie must meet for commissioning. The next part deals with computer modelling and analyses of a frame of this modified freight wagon bogie. It was analysed using the FE method and calculations were focused on the assessment of stresses of the frame structure under exceptional load. Calculation conditions were based on valid standards.

Abstract:In this article the strength analyses of weights boxes are presented. Boxes are designed as a welded steel structure at which weights with total mass almost ten tons are stored in them. These boxes are an integral part of a mechanism intended for calibration of the mass measurement device.The article contains on one hand the basic scope of the theory of elasticity and strength analysis and on the other hand the numerical computations of the structure by using the Finite Element Method.Based on results the structure of weights boxes was modified in order to satisfy the defined safety factor.
