Opis:: The lorry frame is the main carrying part of a lorry, composed of several components. These components are connected by joints into one structural unit and it forms the lorry chassis. The contribution of this article is focused on thestrength analyses of a backbone frame, which is used on an off-road lorry chassis. Strength analyses are carried out utilising the finite element method. This article presents a created three-dimensional model of the frame and definition of boundary conditions (loads, the definition of degrees of freedom) needed for simulation computations. Results of the numerical calculations are the main parts of this article. Attention is mainly centred on the distribution of stresses of the frame under defined loads and its deformations.

Opis:: A trailer for carrying a small boat or water scooters was designed for a private sector company. It was a category O1 non-braked trailer with a gross weight up to 750 kg and a height-adjustable traction device. The frame must be designed and installed in such a way that, during its proposed lifetime, it will withstand all the loads and influences that may occur during construction and operation with an appropriate level of reliability. The designed frame of the trailer is a welded galvanized structure. The article is devoted to the problems related to the stress analysis of a trailer frame.

Opis:: Nowadays, the importance of maintenance and effective use of available railcars in the railway transport is growing, and researchers and technical experts are working to address this issue with the use of various techniques. The authors address the use of analytical technique, which includes mathematical solutions for flexural and longitudinal fluctuations of the bearing framework of a railcar body frame. The calculation is performed in connection with the modernization of the body frame of emergency and repair rail service car, taking into account the variability in section, mass, longitudinal stiffness, and bending stiffness. It allows for extension of the useful life of their operation, with special focus on vehicles owned by Joint-Stock Company "Uzbekistan Railways". The simulation of equivalent bearing body frame of emergency and repair rail service car was carried out using an elastic rod with variable parameters including stiffness and mass. The difference between the proposed model and the existing ones is due to the variability in cross section, mass, and the longitudinal and bending stiffness along the length of equivalent beam, which corresponds to the actual conditions of operation and data of the experimental studies conducted by the authors on the bearing frames of electric locomotives’ variable sections. The frequency analysis that was carried out with the use of the Mathcad 14 programming showed that the frequencies of natural oscillations change on n harmonicas = 1, 2, 3 … 5. As regards longitudinal oscillations of system, in case of introduction of the damping subfloor, the frequency of natural oscillations of the upgraded rail car frame λ1mn increases on comparing with standard λ1n (for example, in case of n = 5 the frequency is 0.587 and 0.602 Hz/m, respectively).
