Abstract
Spatial filter whose importance has been recognized is useful for suppressing modal observation spillover and making reduced-order model of the structures. The authors have proposed a design method of spatial filter of structures. A small number of sensors are used to design spatial filter that are below number of the modes in target frequency range. In this paper using the experimental modal vectors redesigns the temporary spatial filters based on the analytical modal vectors. This paper installs the evaluation of optimal sensor position for establishing spatial filter. The workability of the method is investigated by experimental application to a cantilever beam.
