Abstract

The article is devoted to the problem of modeling the process of manufacturing a power cladding of composite fuel tanks obtained by the winding method. When studying the process of winding a fuel tank, much attention is paid to the formation of its bottoms. The formation of a massive pole thickening in the load-bearing shell, which is created during the pole rotation near the choke, creates not only excessive weight of the structure, but also creates significant axial forces. The gradual retraction of spiral layers and the creation of zoning can significantly relieve this part of the structure. In this case, the task is to correctly calculate and graphically display the obtained layered structures. The task becomes more complicated when studying the issue of winding the ends of a complex shape. To solve this problem, the process of graphical construction of the shaping of the power shell of a lineless composite fuel tank with a small pole hole is considered. The model is based on a mathematical representation of the forming mandrel function for the first layer, and iterating it for subsequent ones, taking subsequent surfaces as reference. To implement the model, 3D CAD systems are applicable, which allow working with functions and parameterization. High attention is paid to the problems of forming the winding surface of the layers of the power shell in the area of ​​the pole hole, including for fuel tanks with bottoms of complex geometry. The effectiveness of the structural and technological decisions is confirmed by the nature of the destruction during the tests. The resulting model was confirmed during the manufacture of an experimental design.An assessment of the results obtained and conclusions on the work done are presented.
