Analytical
Techniques for Evaluation of Compressor-Manifold Response
J. C. Wachel/F. R. Szenasi, ASME Paper 69-PET-31, 1969.
This paper discusses
the types of vibration and stress problem encountered in reciprocating
compressor-manifold piping systems and mathematical analysis methods
and digital computer programs developed in the research sponsored
by the Pipeline and Compressor Research Council of the Southern
Gas Association. These techniques can be used to calculate natural
frequencies, mode shapes, vibrational amplitudes, and dynamic stresses
caused by acoustical and mechanical excitation forces in the system,
and they have been used in the design of domestic and foreign compressor
installations representing well over 10 million installed horsepower.
Comparison of these predictions with experimental field results
has shown that accurate estimates of dynamic stress and impending
failures can be obtained.
