Structural Dynamics

The finite element (FE) method is well-established for static and dynamic analysis of structures, and several outstanding commercial programs are available. ØDS uses state-of-the-art-tools for FE analysis, including ANSYS® and I-deas®.

Furthermore, ØDS has developed an in-house FE code for special applications. It is our experience that many vibration problems can be avoided or resolved with the correct use of FE analysis and correlation with measurements on the physical structures where it is possible. Typical assignments involve:

• Dynamic analysis of global and local marine structures
• Dynamic analysis of machinery structures and foundations
• Torsional and lateral rotor dynamic analysis
• Modal analysis and identification of operational deflection shapes
• Static and dynamic strain and stress
• Fatigue life calculations
