Cost-effective and detailed modelling of compressor manifold vibrations
article
In systems with large reciprocating compressors, so-called compressor manifold vibrations can contribute to fatigue failure of the pipe system. These vibrations are excited by pulsation-induced forces and by forces generated by the compressor. This paper describes an advanced and accurate method for predicting vibration levels and cyclic stresses in critical parts of the piping, based on detailed modelling of the pulsations and compressor parts. Although detailed finite element modelling is applied, the method can compete in ease of use with analytical methods and is far more accurate. The effectiveness of this approach will be demonstrated by a case study in which a detailed compressor manifold vibration analysis has been carried out.
