Structural analysis

DLK uses both conventional strength calculations and numerical structural analyses using FEM (Finite Element Method) to verify the strength of the fan.

In addition to the strength verification of components, analyses of complete systems are also carried out, i.e. the interaction of the various assemblies is assessed. Within the framework of structural analysis, component connections such as welds, screws or rivets are designed for their fatigue strength. The determination of stresses and strains due to thermal and mechanical loads in the component play a major role. In addition, the vibration behaviour is analysed to ensure low-vibration operation of the fan.

Both in the development of new products and in the further development of the existing range, structural analyses are used to optimize the factors of strength and efficiency. In addition, the use of new materials is being examined.
