Computer Aided Engineering (CAE)

FINITE-ELEMENT-METHOD (FEM)
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.

EVIDENCE

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

MULTI-BODY SIMULATION (MKS)

We will design the kinematics in accordance with the specifications regarding the positions to be achieved and the available construction space. We also take care of calculation of the required drive data and the present bearing points.

OPTIMISATION

Optimisation is one of the most important aspects today. Virtually every design can be adjusted in some form to optimise its conditions. In the first step, we will optimise the structure and perform carrier calculations. Smart use of various methods helps us find the optimal combination of rigidity, longevity, and weight. We use our competence in the finite-element-method to improve complicated structures. We also use topology optimisation separately from the classical optimisation of shape. The numerically most rigid structure for specified decision-making criteria, such as a defined load case and a desired mass, will be determined in this.
