Abstract
Abstract. This article is devoted to the study of the possibility of replacing a flat web in runway beams with a corrugated one in order to increase the reliability and stability of welded joints. In the study, an analysis of stresses in the structure of two types of web outlines was carried out, the features and advantages of corrugated webs were revealed. The article provides a detailed overview of the analysis results, demonstrating how a corrugated structure can effectively prevent the separation of welds under the influence of loads. The reasons for choosing this method and its practical applicability in industrial conditions are considered in detail. The study involved a computer experiment, including calculations using the Tonus PC SCAD post-processor, as well as the Lira-SAPR 2022 PC. The stages of the experiment include calculations of the geometric characteristics of various web shapes in the Tonus post-processor, modeling of three-dimensional runway crane beams with flat and corrugated webs, calculation and determination of the maximum normal stresses in the web in PC Lira-SAPR 2022, comparison of the results of beams with flat and corrugated webs and interpretation of the results, and substantiation of conclusions based on the data obtained. The authors highlight the prospects for the application of this approach in various fields of industry, emphasizing its importance for ensuring the safety and durability of crane girder structures. The results obtained are the basis for further research and practical implementation of innovative solutions in the design and operation of industrial facilities.
