Digital modelling
Digital modelling is tending to become an essential feature in product development. Use of the virtual model allows for considerable gains in terms of efficiency and development time.
The calculation base used is IDEAS. It is, however, possible to retrieve models developed using other software, as with NASTRAN, ABAQUS, ANSYS, etc.
- Calculation of stresses and displacements under static and dynamic loads.
- Optimisation of vibratory behaviour and acoustic radiation of products in the design phase.
Tools and methods:
- 3D or surface modelling
- Calculation by conventional finite elements for structural analysis and for closed domains.
- Use of border finite elements for acoustic radiation problems and coupled fluid/structure and internal/external problems.
Range of results:
- Von Mises stresses
- Displacements
- Structural quadratic acceleration and speed
- Pressure, acceleration, acoustic intensity
- Structural modal contribution
- Radiated acoustic energy
- Energy dissipated in the structure by damping effects
- Kinetic energy and structural deformation
- Power injected by mechanical excitations
