Node Velocities on a Harmonic Analysis
Node Velocities on a Harmonic Analysis
(OP)
The output I have is only nodal displacements.Is the maximum velocity the displacement multiplied by the angular frequency(rad/s) or by the frequency(Hz)itself?
Also,can someone explain it physically??Why not the displacement divided by T(period)/4?
Thanks
Rafael

RE: Node Velocities on a Harmonic Analysis
I don't think you can take a static displacement and get a maximum velocity using the natural frequency of your structure. What force or analysis did your displacements originate from?
RE: Node Velocities on a Harmonic Analysis
I ´m taking displacements from the Harmonic analysis, and I ´m multiplying it by the Turbine´s frequency, not the structure natural frequency.
