Computer Aided Engineering (CAE)
In times of industry 4.0 and “digital twins”, FEM is one of the most important tools in order to determine any shifts and tensions of parts that arise even in the design phase. We generally perform plausibility checks in order to verify our FE analyses. We distinguish between two types of FE calculations depending on task.
1. STATIC IMPLICIT CALCULATION
This examines the stress on a design in clearly defined load cases. Service life calculations can be performed in the further course based on these results. Movement studies at slow speeds can be implemented this way as well.
2. EXPLICIT CRASH CALCULATION
Highly dynamic issues such as impact on a fixed stop, or “what if?” analyses can be solved this way.
Many standards and provisos require defined safety measures or minimum service lives to be achieved. These values will be calculated based on different kinds of evidence, depending on the part at hand. We can provide the following kinds of
- Lifetime evidence/permanent durability evidence in accordance with FKM directive 2020 for general machine parts (upstream FE analysis necessary)
- Shaft evidence in accordance with DIN 743
- Screw evidence in accordance with VDI 2230
