Reciprocating compressors are un- Aavoidable classical solutions in the field of natural and process gas compression with the ability to function over a wide range of operating conditions. The dynamic design of the reciprocating compressor is complicated due to the large number of conditions that have to be satisfied. Since, high torsional dynamic stress is often not recognised until damages appear, it is advisable to conduct a detailed torsional vibration analysis when planning a new drive train or modifying an existing one. In this article, the different causes for torsion related coupling damages are shown and reduction measures to influence the torsional behaviour of reciprocating compressors are presented with the help of case studies.
