Carrying out calculations and analyzes

We work on various structural mechanics topics, from substantiated stress determination to detailed strength analysis. We are very happy to help you with initial obstacles for "simulation newcomers" of medium-sized companies and offer staggered service packages. As specialists in structural analyzes with the help of the FE-method, we are able to perform complex calculation tasks with coupled thermo-mechanical problems in particular, taking into account contacts and USER- subroutines.

Beside model creation (geometry, mesh Generation, boundary conditions), we offer following calculation types:

  • Linear and non-linear statics with component contacts, temperature field calculation
  • Transient dynamics (case analyzes/ virtual drop tests)
  • Strength analyzes (fatigue loads, static loads)
  • Eigenfrequency analysis, Campbell diagrams
  • Stability: bending and buckling
  • Verification with analytical methods and validation based on experimental data
Example: strength

Static and dynamic proof according to FKM-guideline

The FKM-guideline (FKM = Forschungskuratorium Maschinenbau) is the standard in many industries for the design of machine components and includes the calculated strength proof verification. The strength verifications (static and fatigue strength) are based on the calculation of stresses as a result of FE analysis, assuming linear material behavior. Upon customer request, further regulations can be used to evaluate the strength.

Example: stiffness

Stiffness proof / permissible elastic deformation

In addition to the strength, light weight constructions must usually also be checked for permissible deformations during load suspension. The necessary stiffness is defined by the material properties (e.g., modulus of elasticity) and the given geometry (e.g., shape of the cross-section).

 

Example: vibrations

Modal analysis: Eigenfrequencies and eigenmode

The results of the modal analysis are eigenfrequencies and eigenmodes and represent important parameters for the design of a structure regarding dynamic loads or vibration tendency as well as resonance avoidance. In addition, if the excitatory frequencies are known, the Campbell diagram provides an important overview of vulnerable operating areas of the design. The simulation results thus give an indication of necessary design changes.
