Measurement of structural intensity on beam structures
Keywords:Acoustic transducers, Acoustic wave velocity, Approximation theory, Beams and girders, Plates (structural components), Beam structures, Point spacing, Structural intensity
AbstractA scanning laser vibrometer and specially developed analysis software were used to systematically investigate the optimal point spacing, and the suitability of measurement quality indicators, such as the residual intensity index, for the two and four point methods. In addition, the sensitivity of the two-transducer to near fields close to sources and discontinuities was examined. The resulting data was analyzed.
