FEM Analysis

For strength / acoustics / dynamics:

Calculation using the Finite Elements Method

Parts characteristics can already be examined and analyzed before the part is actually being manufactured.

Simulation instead of trial-and-error !

  • examine and analyse parts characteristics before part is actually being manufactured
  • ensure collision observations using work movements
  • verification using computer tomo­graphy possible

In the example to the right, an increase (> 50 %) of load capacity of an oscillatory element was obtained after part optimisation verified with FEM.

For example, we look at:

– sealing behaviour 
– acoustics
– thermal insulation
– dynamic deformation
– considerations redarding strength
– unwinding behaviour

The “Finite Elements Method” is a calculation method from engineering that can demonstrate important potential for optimisation or verify improvements. Different functionalities such as the sealing bahavour or the possible load of a part can be examined before the part is actually being manufactured and optimisations can be implemented in time. FEM can be used for almost any material (e.g. metal, glass, plastics).

For an FEM analysis, we need 3D data of the part, load definitions (where can what kind of force be expected?) as well as a stress-strain curve of the material.

FEM systems for calculating strength are generally divided into “linear“ and “non-linear“ approaches. The “non-linear“ approach is closest to reality for plastic parts.
