Abstract:Abstract.The article provides an overview of software designed to perform the simulation of structures, calculate their states, and respond to the effects of loads applied to any of the points in the model. In this case, we are interested in the possibility of modeling the locomotive chassis frames, with the possibility of determining the weakest points of their construction, determination of the remaining life of the structure. For this purpose, the article presents a developed model for calculating the frame… Show more
“…The driving time of a shunting locomotive with a group of wagons or separately, depending on its mileage and the requirements of regulatory documents, is determined by the following formula [2,[7][8][9][10][11].

“…Several scientific results have been achieved in the course of the research conducted in the world to improve the technologies of transport processes in the organization of shunting operations; in particular, fuel injection systems of shunting locomotives have been modernized, systems have been improved to increase the processing capacity of mainline and industrial railways, locomobiles have been introduced to deliver wagons to cargo facilities, traction units have been developed to push wagons to a warehouse or conveyor belt during loading and unloading operations, solar energy use systems have been created to reduce the energy consumption of shunting locomotives [1][2][3][4][5][6][7][8][9][10][11][12][13].…”
It is known that one of the main factors reducing the shortage of shunting locomotives at railway stations and leading to a reduction in their employment time due to increased labor productivity is the state of equipment of the railway station infrastructure with SCB devices. This article presents a way to attract low-mobility shunting locomotives by reducing the duration of employment of shunting locomotives allocated for the daily amount of work performed at the station when equipping them with devices by changing the infrastructure of an electric decentralized railway station. A comparative analysis of the time spent by the shunting locomotive in motion during the day when performing each technological operation for the maintenance of cargo facilities, as well as the amount of time spent on additional actions, is carried out.

Section: Modelling the Freight Wagon Multibody Systemmentioning
Computational modelling and simulations are nowadays widely used for design of railway vehicles, analysing and assessment of their dynamic properties and also for detection and prediction of the mechanism of deterioration and sources of damages. Therefore it is necessary to develop the adequate virtual model of an analysed railway vehicle as well as a track. For these purposes many simulations software packages are developed. In these computational programs a railway vehicle is modelled as a mechanical system usually consists of many bodies called a multibody system. In this paper the process of computational modelling of a freight wagon multibody system is outlined. Moreover, there are presented also results of dynamic simulation of a freight wagon running on a real track section. The analysed intermodal freight wagon was equipped with Y25 bogie. The freight wagon model, simulation analyses and ride properties evaluation were performed by means of a commercial simulation program.
This article presents an engineering design of a mechanical rack system along with strength analyses of its main load-bearer parts. The designed mechanical rack system is intended to be mounted in a production hall for storage of rod material with total length of 6 m. The whole structure of this equipment is welded and made of steel profiles. It consists of a main load-bearing part, which comprises a central beam and horizontal beams and four draw-out shelves on each side, which are arranged four levels. Every individual shelve is able to carry the mass of 3.0 t. As the solved rack system is not standardized but designed in compliance with specific requirements of a customer, we had to support the structure carrying capacity with strength calculations. Structural calculations were realized by means of numeric finite element method. Strength analyses were performed for the maximum load cases.
