12 Mechanical Analysis

Mechanical analysis entails a number of common and related aspects of pumping and compression as they relate to rotating equipment, both drivers and driven equipment, and its interaction with attached piping systems. The various combinations of driver and driven equipment pose unique problems with respect to their rotordynamics that have to be recognized and mitigated by the designer. These include both lateral and torsional rotordynamic effects. In addition, the pumping or compression process may impact the associated piping system, or conversely, the rotating equipment can be adversely affected by piping design. All of these factors, therefore, are important for both the designer and operations and maintenance.
