“…We will create a mechanical system of a modified bogie in a multibody software and our just analysed FE model will serve as an important input for setting up a multibody system with a flexible body in order to study its dynamic properties and to compare with the original bogie for the detection of possible problems in terms of long-term operation [29,30].…”

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.

Design of a Metro Door System and Determination of Main Loads

This article discussed the determination of a metro vehicle's door forces acting on its coarse structure. With previous articles addressing this issue, a definition of a specific reference vehicle was provided together with the collection of the normative requirements for metro vehicles. These form a basis for addressing the issue. The main objective hereof was to design a technical solution of a door system for the reference vehicle and create a parametric model of the door's forces acting on the vehicle's rough structure. This model would serve to approximate and operatively quantify these force effects of the door to the vehicle's structure by modifying the various input parameters. Therefore, it was necessary to create a mathematical model of the equilibrium conditions of the proposed door system and to quantify them using a developed software. Subsequently, these results served as inputs for the FEM analysis of the load-bearing components between the door and the vehicle's structure.

“…Rail vehicles properties as a mechanical system can be designed, studied, evaluated and verified by means of experimental methods and measurements in real operation or in laboratories conditions using special equipment [7][8][9]. Another approach based on numerical methods allow to create virtual models of rail vehicle subsystems [10,11] or whole rail vehicle and even rail units and trains [12,13] (Fig. 1).…”

The railway transport network is currently in a quite big expansion. Therefore, railway tracks are modernized and the attention is given also on the technical state of rail vehicles, which operate on them. However, it may happen that the wheel surface is damaged. One of the most common reasons of wheel damage is too much braking, which results to the wheel-flat formation. This article is focused on the evaluation of the influence of a rail vehicle running on the railway track, which a wheel is damaged by the wheel-flat. Investigation of these negative effects was performed by means of simulation computations. As evaluating parameters, values of the wheel force in the contact of the rail and wheel with a flat where observed.
