Software for Damage Calculation - DACA

We mainly work in the field of classical mechanical engineering, special mechanical engineering and rail vehicle technology. The tasks range from calculation and verification of individual components to the design and calculation of complete assemblies, machines or special test benches. Especially in the field of rail vehicle technology, we provide profound Know-how for the development of suspension elements made of elastomeric materials. Our software DACA specially programmed for the service life calculation of elastomer materials has been successfully used in a number of projects. In particular, safety-relevant components for rail vehicle technology have been designed and calculated using finite element analysis - FEA - and their suitability for use has been proven on the basis of load assumptions and/or data from operational measurements.

DACA - software for damage calculation by Engenium

For the visualization of the FE results and especially for the damage calculation of elastomer components we have programmed an evaluation routine with an independent GUI. For the damage calculation, the corresponding stress and/or strain values for the reversal points of the load signal reduced by means of omission are calculated with the help of the FEA. The results of the 3D support point space  and the applied damage hypothesis is counted by means of a Rainflow algorithm and damage is evaluated according to the underlying Haigh diagram.
