| Summary: | Заглавие с экрана Изложена методика анализа прочностных характеристик конструкции секции става скребкового конвейера, работающего под действием системы внешних сил, обусловленных совместной эксплуатацией в очистном комплексе при добыче угля. На основе результатов оценки напряженно-деформированного состояния секции приводятся рекомендации по совершенствованию ее конструкции. Предлагаемые решения обосновываются и подтверждаются сравнительным анализом прочности элементов секции. Purpose. The article is devoted to the approbation of a computational methodology for analyzing the strength characteristics of a section of a scraper conveyor, taking into account the external impact on the section from elements of a mine treatment complex used in coal mining. Elimination of structural defects of the section is carried out, as a rule, by simple means of increasing the size of its elements. The presence of a generalized technique for analyzing the strength of the conveyor section ensures a rational choice of materials and geometric elements of the section at the design stage.Methods. The developed method of analysis of the stress-strain state of the section of the scraper conveyor is based on the application of the method of finished elements, which is the basis of automated systems of engineering calculations. The created design model of the section makes it possible to determine the strength characteristics of the structure depending on the operating conditions and the external system of forces caused by the interaction of the section with other elements of the mining treatment complex.Results. Based on the results of the conducted research, a plan has been drawn up to optimize the design of the conveyor section, the implementation of which ensures an increase in structural strength and, consequently, an extension of the service life of the conveyor. The obtained results of computer calculations are quite correlated with production data on the assessment of the failure of conveyor sections as a result of the destruction of structural elements.Conclusions. The developed computer model of the section of the scraper conveyor, when implementing the proposed methodology for analyzing the strength characteristics of the structure, ensures the selection of rational geometrically and technological parameters of the section at the design stage. |
