3 Evaluation of the Vibratory Properties of the Engine
The response of the structure to the internal forces, the structural mode shapes
and the resonant frequencies are some of the vibratory properties
that are useful to the design engineer.
The finite element method is now generally regarded as a reliable tool for
modelling the vibratory behaviour of elastic structures (see, for example,
Zienkiewicz (1977)) and there is continued development of methods for the
calculation of the excitation and response.
The application of such methods
to engine blocks is considered in Croker, Lalor and Petyt (1979),
Lalor and Petyt (1982)
and Tyrrell and Croker (1987).
