Hand calc for verification and validation of modal analysis results
Hi, tell me what the problem is.
Disk modal and harmonic analyses: Steel disk - 75 mm radius and 3 mm radius center hole, and 0.34 mm thickness. Modulus = 200000 MPa, Poisson’s Ratio = 0.3, Density = 7850 kg/m^3. Support: simply-supported, (no translation: UX = UY = UZ = 0) at the edge of the hole.
- Calculations do not match.
- The Freq_Target-parameter (frequency target for modal simulations) does not affect the calculations.
