FEM (finite element analysis)

Mechanical components are exposed to different kinds of strain and have to fulfil high demands regarding their strength. With the usage of FEM the static strength and the fatigue strain of various components can be inspected and designed.

Working steps and services

Therefore, the relevant component as well as their neighbouring components and their boundary conditions are modelled as realistic as possible. Appearing non-linearities, caused for instance by bearing or screw joints, can be taken into consideration. The mechanical behaviour of a structure can be reproduced much more realistic by that.

In case a vibration analysis of the structure becomes necessary natural frequencies and natural modes can be determined with FEM.

All we need from you for an FEM-Analysis are geometrical data in form of a technical drawing or as a CAD-file, the material in use and the boundary conditions, like bearing and loading.

Selected services in this context:
  • FEM-Calculation of mechanical components of all types
  • linear and nonlinear structural and stress analyses
  • Analysis of structures made of fibre-plastic bonding (for instance GFK, CFK)
  • Modal analyses
  • Buckling analyses
  • Programming of APDL macros for automation of the workflow and for modelling of parametric structures
ANSYS-Macros

Within ANSYS the workflow can be automatised trough the APDL language respectively results can be exported in a desired format. In the course of time at Rotorwerk several APDL marcros where developed in order to facilitate the daily work with ANSYS. Some of our APDL macros we want to provide tho the user of ANSYS.
