โœฆ Synopsis

A convenient and eective ยฎnite-element-based method for bueting analysis of complex structures is presented. This method is very ecient for structures with the natural frequencies closely spaced because their corresponding modes and the cross-correlation terms between them should be included in the modesuperposition analysis. The imperfect correlation between gust excitations can also be dealt with conveniently. A numerical example is given which shows that by using this method the bueting analysis of complex structures with thousands of degrees of freedom, dozens of imperfectly related excitations and a number of participating modes can be executed quite easily on an ordinary IBM/486 (or 586) personal computer.

In this paper, we present a technique, based on the principle of the frequency-domain conยจolution of a time-domain signature and a truncation window function, to process the electromagnetic field solution in a resonant structure deriยจed by using the finite-difference ( ) time-domain FDTD algorithm.
