Scheme of reinforcement of a part of a complex geometric shape on the example of an axial fan

The article discusses the design of a reinforcement scheme for a complex part, which was chosen as an axial fan. When designing a part or structure, the developer is faced with the task of determining which of the methods of manufacturing the part should be chosen, cast or prefabricated. For comparison, two cases of constructing a geometric shape are considered. In the first version, the fan is made of a single material without gluing; in the second, the design is made from the assembly of components. Comparing the stress and displacement patterns of the two fans, a difference was noticed in the attachment points of the blades to the impeller. In the second variant, due to the gluing of the blades, additional stresses arise at their base. Which in turn leads to additional reinforcement trajectories. It should also be taken into account that when manufacturing a part as an assembly unit, reinforcement trajectories must connect adjacent components to reduce stress at the points of their bonding.
