Problem Statement: On the HTFS Resonance Analysis table, when tubes report a Turbulent Buffeting ratio (Ft/Fn) between 0.8 to 1.2, they are marked with an asterisk, as possible vibration problem. However, no Turbulent buffeting amplitude is reported. What is the reason for this? | Solution: When the natural frequency is high (i.e. grater than 88Hz) it yields zero amplitude according to the TEMA method calculation for Turbulent buffeting amplitude. When using the HTFS method, Aspen EDR does not report the zero amplitude value as it is not physical.
In the same way, the Resonance Analysis only rep... |
