COMPARATIVE ANALYSIS OF CALCULATIONS OF STRENGTH OF PNEUMATIC PIPELINES: ANALYTICAL METHOD AND APM WINMACHINE

The article presents a comparative analysis of the strength calculations of pneumatic pipelines performed using the analytical method and numerical modeling in the APM WinMachine environment. The theoretical foundations of strength calculations of cylindrical shells are considered, analytical formulas and their practical application are given. The stresses and displacements of the pipeline under specified loads are determined based on numerical modeling. A review of scientific publications related to the strength analysis of pneumatic systems is performed, key calculation methods and their features are highlighted. It is shown that the use of APM WinMachine makes it possible to obtain more accurate results by taking into account geometry, boundary conditions and local stresses. The results obtained confirm the need for an integrated approach to the calculation of pipelines for strength in this area, and the results are also used in practice
