“…The analysis of the theoretical and experimental research into the strength characteristics of rail vehicles by an example of the centre sill of a freight car is given in [5] in which the authors applied modern software programs. This approach turned out to be effective and efficient, i.e., the authors found the right area in their research.…”

This article presents the most frequent damage in the bearing structure of a rail car during rail/sea transportation. The study includes load modes for the bearing structure of an open car such as unloading with a grab and transportation by a train ferry. It was found that the most vulnerable element of the bearing structure of an open car during unloading with a grab is the top cord. The authors suggest applying a viscous material (an elastomer) to reinforce the top cord. This solution was confirmed by means of a strength calculation, whose results showed the efficiency of the solution. The bearing structure of an open car during the train ferry transportation can be protected by mounting special fixation units on the bolster beams. The geometry of such units was chosen according to that of a chain binder. The results of the strength calculation demonstrated that the strength of the bearing structure of an open car was provided with the application of the fixation units suggested. The article also presents the results of the experimental determination of the strength of the improved bearing structure of an open car based on the finite element method and full-scale bench testing. The research conducted might be used by those who are interested in higher operational efficiency of rail cars during rail/sea transportation.

“…To perform all these variant calculations, we used extremely popular in recent decades and tested numerical method of construction mechanics. It is the finite element method [12,15,17] based on the widely known domestic software complex Lira for Windows [11]. The constructed design model for the basic structural variant of the production building is shown in Fig.…”

Purpose. Recently, there has been a growing demand in Ukraine for the reuse of industrial buildings that have not been in exploitation for a certain period of time. At the same time, there are frequent cases when new technological equipment transfers significant dynamic loads to existing structures over a long period of time. Since the available data regarding the dynamic properties of industrial buildings are now practically absent, the main goal of the studies made by the authors is to evaluate and analyze own dynamic characteristics of a one-storey industrial building. Methodology. To achieve this goal, it was necessary first to choose the type of industrial building, which is common enough for the formulated conditions of the reuse possibility. A one-storey unheated industrial building with three purlins (purlins 15 + 15 + 6 m) with a steel supporting frame was taken as such a building. In the course of research, the cross sections of the main load-bearing elements were varied, as well as the schemes of their connection with each other. The calculations were carried out by the finite element method based on the Lira for Windows project complex. Findings. The obtained frequency spectra of the own dynamic characteristics for the main bearing structural elements of an industrial building of the type in question are in the range up to 30 Hz. Also, during the research, dependencies were obtained for changing this range for various cases of design decisions of the building. Originality. The research results presented in the publication make it possible to evaluate the range of the own dynamic characteristics of single-storey multipurlined unheated industrial buildings with the traditional structural solution of the steel frame. Practical value. The resulting range of the own dynamic characteristics of the industrial building of the type in question is quite dangerous for human health. The most unfavorable is the oscillation form of the columns, which actually involves the entire structural frame. Therefore, in the course of research, a special method was developed and tested to stabilize such vibrations «on the base» using flexible ropes.

Rolling stock directly affects the economic indices of the transport industry and the national economy as a whole, leading to the need to improve control and quantify of the rolling stock dynamic load in order to maintain safe and reliable rail connections. In the process of rolling stock designing and operating, a quantitative assessment of dynamic loads is an urgent scientific and technical problem. The article presents an analysis of theoretical studies of the rolling stock dynamic characteristics on the example of open wagons, flat wagons and hopper wagons. The loading modes influence on the dynamic loading of the wagon has been studied with the aim of solving the problem of predicting the dynamics of rolling stock and indicators of its interaction with the track. The results of theoretical studies are presented taking into account the motion speed along the curved track of short and medium radius.
