| Summary: | 碩士 === 國立清華大學 === 動力機械學系 === 84 === Owing to the characteristics of joints with decisive effects on
a structure, it is necessary to have a method to identify the
parameters of joints precisely. In this paper,we mainly
improved the method on Ref.【10】、【11】 . Because that it can
identify the parameters of the joints by directly measuring the
frequency response function of a struc- ture, the above-
mentioned method is expensive. We employed the concept of
weighting to make use of the experimental data suff- iciently
and derive the relationship of the frequency response function
of a structure and the sensitivity of the parameters of the
joints. With the aid of the sensitivity of the parameters of
the joints, we can choose the frequency correctly and make the
results of identification of a structure precisely. The
condition of a structure with a low sensitivity have to be
changed. The method of promoting the sensitivity within the
range of frequency which we are concerned are discussed in this
paper.
