MMRB-Repair-Care
Official Project Name: "Multivariate Damage Monitoring of Rotor Blades: Implementation and Analysis of the Effects of Repair Measures“
Subproject: "Optimisation of Vibration-Based Monitoring for Repaired Rotor Blades“
Laufzeit: August 1, 2022 – July 31, 2026
Geschäftsfeld: Offshore Wind Energy
______________________________
Within the collaborative project MMRB-Repair-Care, Wölfel and its partners are developing advanced methods for intelligent condition monitoring of wind turbines, with a specific focus on previously repaired rotor blades. Building upon the predecessor project MultiMonitorRB, the consortium investigates how repair interventions affect structural integrity and service life. The objective is to optimise vibration-based monitoring systems to ensure reliable condition assessment and precise lifetime predictions even after repairs have been carried out.
Project objective and description
The MMRB-Repair-Care project addresses a highly relevant issue in the field of wind energy: How does the structural behaviour of rotor blades change after repair – and how can such changes be reliably monitored? Rotor blades are key components of modern wind turbines and are subjected to enormous dynamic and climatic loads during operation. Repairs are complex and have a lasting effect on the mechanical behaviour of the blades.
Based on the findings of the preceding MMRB project, real rotor blades that have undergone industrial repair measures are re-equipped with measurement technology and tested under laboratory and offshore operating conditions. The aim is to develop and validate vibration-based SHM (Structural Health Monitoring) methods capable of reliably assessing even modified structures. Methods from the fields of data analysis, numerical simulation, and virtual sensing are used. Innovative approaches such as automated referencing after repairs and combined damage indicators are intended to take damage diagnostics and service life assessment to a new level.
