Computer Derivation of Green's Functions for Structural Dynamic Analysis
Abstract
This research program has been concerned with the development of a new generation of computer-aided techniques for the dynamic analysis of complex structural systems. These techniques which use powerful symbolic processors such as MACSYMA are expected to facilitate the derivation and analysis of Green's functions of interconnected distributed parameter structures. The present approach uses integral methods to combine the transfer functions of the baseline structure with those of discrete substructure attachments in order to obtain the transfer function of the interconnected system. This resultant transfer function is then transformed into a form which lends itself easily to inverse Laplace transformation, yielding the Green's function of the interconnected system. Such algebraic results are expected to improve the understanding of the effects of substructure attachments e.g. active and passive vibration controllers, on the dynamics of large flexible structures.
