Abstract

Potentialities of merging contact and noncontact measurement techniques for structural analyses are studied in this paper, to explore limits and advantages of classical and innovative techniques (accelerometers, Laser Doppler Vibrometer and microflowns pressurevelocity probes). The analysis refers to a previous experimental campaign, devoted to a specific test case in a modal analysis environment; this appears as a suitable and representative field of application for the goal of highlighting possible correlations to the benefit of a robust comparison among resulting indications coming from different transducers. Methodological suggestions, addressing future and more focused measurement campaign, post-processing algorithms and optimization procedures are provided in this paper. They will be used also for defining a more systematic experimental campaign to be carried in order to identify possible guidelines for both fusion of sensor indication and more complex structural characterization.
