Hi,
We are currently using Caesar II s/w for Dynamic analysis of Piping Systems. We have a problem on a GAS Compressor which needs Harmonic Analysis. Kindly let us know the source for the following input data :
1. Starting & Ending Frequencies. Is the Starting Frequency the one that causes the max. displacement as measured in the field? What is the Ending Frequency then? & also what is the Frequency Increment.
2. What is the source for the Harmonic force and how is it measured. Is this calculated similar to the unbalanced forces for the Hammer Analysis based on the Differential Pressure and sonic velocity.Please clarify the criteria for compressible fluids(Gas).
3. Please also tell us how to determine Load Cycles & Harmonic Displacements
