SIMBEAM Rotorblade Generator – Validation<br />
• Eigenfrequencies identical (NASTRAN)<br />
• Excellent comparison results obtainable<br />
Important Points to Consider for Comparisons<br />
• Many different interpolation methods (<strong>SIMPACK</strong> Rotorblade<br />
Generator <strong>and</strong> FE codes)<br />
• SIMBEAM elements always along neutral axis<br />
• For twist/bend coupling a small border for “Zero Elements”<br />
required in FEMBS (e.g. 10.e-10)<br />
• A large number of modes should be considered for stability<br />
calculations<br />
