The pursue of methods for supporting Structural Health Monitoring (SHM) hasbeen an important driver for the technological innovation in several engineering fieldssuch as wireless communication, sensing and power harvesting. However, despite ofthe innovative and scientific value of these advances, the adoption of SHM andassociated technologies by industry has not occurred at the expected pace. One of thepossible reasons for this is the lack of a systematic design process for conditionmonitoring systems tailored to actual mechanical systems. This paper proposes adesign framework for a vibration monitoring system that integrates the predictivemaintenance needs with the technological developments on SHM methods and relatedtechnologies.The framework involves three stages. The first stage corresponds to theidentification of the characterization of the system function and its failure and theexpected function of the monitoring system. The next stage aims at decomposing thevibration signal according to the dynamic behavior of the system and associatedfailure. The last stage corresponds to the technological implementation of the vibrationmonitoring system. To illustrate the applicability of this framework a case study on thedevelopment of a vibration monitoring system for helicopter rotor blades by using anautonomous sensor network is presented.
