摘要

Structural Health Monitoring is becoming increasingly attractive for its potentialities in many application contexts, due to improvements brought in by non-destructive test technologies. Among them, Operational Modal Analysis is an efficient tool to assess the integrity of vibrating structures. This work exploits both novel MEMS accelerometers and piezoelectric devices to extract strictly synchronized modal parameters. The advantages of using a combined approach are proved by highly coherent results from an instrumented cantilever aluminum beam, which is able to provide exhaustive structural information.
