Simplified dynamic analysis of the generator

Research output: Book/ReportReport

Abstract

The starting point is that there is no knowledge available of behaviour of the baseframe, the diesel engine, or excitations of the target diesel aggregate. It is presented how a generator can still be designed for a dynamic environment caused by the common baseframe of the diesel aggregate. The idea is to use a selected set of base motions to excite the generator and then scale selected natural modes to the acceptance criteria. The scaled modal responses are used as if they had been calculated with known excitation. When relevant base motions and natural modes are checked a good understanding of the risks to the generator is achieved.
