Abstract

Measurement of vibration or pressure pulsation data on a prototype machine may be performed in order to verify compliance with guarantee, or in a monitoring process or, in some cases, to provide data for root cause analysis if the dynamic behavior is deemed unsatisfactory. It may occur that the nature of a problem is not immediately clear and testing has to check for several possible aspects. This chapter therefore presents a number of practical cases separated from the pertinent chapters. The logic of finding the facts and possible solution strategy based on the underlying physical phenomena is demonstrated.
