“…In recent years, there are more and more research studies on the remote control of port machinery, and wireless monitoring has become a necessary breakthrough topic to achieve the economic development of the port [4]. In port production and operation, the technical level of various lifting and transportation machinery as loading and unloading equipment plays a decisive role [5]. However, the maintenance and management of various loading and unloading equipment mainly depend on the experience of equipment-related technicians.…”

In order to solve the problem that there is a huge amount of port machinery operating state data, the traditional fault diagnosis method is difficult to effectively obtain the mechanical fault information from the massive data and also cannot accurately diagnose the fault. This paper presents a fault diagnosis method for port machinery based on the FastAP algorithm. By analyzing the characteristics of the FastAP algorithm, the algorithm is introduced into port machinery fault diagnosis, and a port machinery fault diagnosis model based on FastAP is proposed. Through simulation experiments, the algorithm and its application in port machinery fault diagnosis are verified. The experimental results show that compared with the standard AP algorithm, the FastAP algorithm performs well in the sum of similarity, clustering accuracy, and clustering calculation time and has better performance, which is more suitable for fault diagnosis. The fault diagnosis method based on the FastAP algorithm has a high diagnosis accuracy of port machinery fault, reaching more than 92%, and can accurately diagnose the normal state, inner and outer ring fault state, and rolling element fault state of the actual port mechanical belt conveyor. The research on remote control and fault diagnosis of port machinery equipment based on wireless communication technology can effectively solve the problem that there is a huge amount of port machinery operating state data, and the traditional fault diagnosis methods are difficult to effectively obtain mechanical fault information from the massive data and thus cannot accurately diagnose the fault.

“…Modern operating conditions of the rolling stock of the railroads in the Russian Federation dictate high requirements for the reliability and durability of its mechanical equipment. The increase in railway traffic speeds and freight traffic volumes, development of territories with severe climatic conditions leads to the growth of loads on elements of traction and non-traction rolling stock, including the crew part [1][2][3][4][5]. The assemblies and parts of modern locomotives are a number of complex and sufficiently diverse in form joints and structures, which accept a large variety of vertical and horizontal loads.…”

The article considers the possibility of using the finite element method for strength calculations of nodes and parts of modern locomotives. There are examples of solid-state models construction of bogie frames in SolidWorks software package. Developed finite-element models allow determining the tense-strained state of the elements of the crew part of locomotives. The final outcome of modeling is the construction of stress distribution diagrams in the locomotive bogie frame. The data obtained as a result of finite-element modeling can be recommended for use when creating new modern units of locomotives as well as for modernizing and increasing the reliability of existing.

In the article, the author published the full-scale experiment results on an existing steel-reinforced concrete road bridge, carried out to determine the actual parameters of the operation regime of the interconnection elements — flexible pin stops. This work was carried out as part of the author's dissertation research in the field of improving methods for testing the elements' endurance of the steel-reinforced concrete superstructures interconnection and is a development of the previously conducted comprehensive comparative analysis of existing models for testing endurance. The article gives a detailed description of the conditions for conducting and methods of a two-stage experiment, which includes short-term and long-term parts, as well as a detailed description used for processing experimental data for each of the stages. Based on the results of the experiment's short-term part, when compared with the results of finite element modeling of the operation of the stops, the possibility of using existing computational models to describe the actual model operation was confirmed. Also, within the framework of the short-term part, according to the conducted dynamic tests results with the moving load passage through the threshold, the presence of a significant dynamic component of the resulting forces in the interconnection stops was revealed. During the second long-term part of the experiment, a continuous recording of stresses in the interconnection elements from the passage of an unregulated traffic flow over the bridge was made. The article presents both direct survey data (tensograms) and the results of their further processing in terms of damage accumulation analysis; also, the accumulated damages values from actual traffic loads are compared with the expected values in the calculation according to some design standards. Intermediate conclusions based on the experiment results are formed and directions for future work within the scope of this study are indicated.
