Oil condition monitoring is a common practice in the wind industry. However, the published research about oil degradation in wind turbine gearboxes is limited. This paper aims at providing new information on the oil degradation process by analyzing wind turbine gearbox oils aged in the laboratory and in the field. Oil samples were analyzed in the laboratory and two sensors were used to. Prognostics is an engineering discipline focused on predicting the time at which a system or a component will no longer perform its intended function. This lack of performance is most often a failure beyond which the system can no longer be used to meet desired performance. The predicted time then becomes the remaining useful life (RUL), which is an important concept in decision making for.

Vibration based damage detection methods are among the most popular and promising approaches for health monitoring of structures. In this work a critical review of different methods for damage. Therefore, local damage detection methodology can only be used to detect some special components of a structure.
In order to detect On-line database of vibration-based damage detection experiments book throughout the whole structure, especially some large, complicated structures, a methodology called global vibration-based structural damage detection, has been proposed.

The vibration based methods that have been proposed for fault detection and diagnosis within the context of non-stationary structures are mainly non-parametric. They usually rely on time-frequency methods, such as the Wigner-Ville distribution (Chengdong et al.
Moreover, it is applicable to beams with any cross-section shape. The relation can be also used to contrive a database, containing numerous damage scenarios, which constitutes a benchmark for damage detection methods (Gillich and Praisach, ), even if composite structures are analyzed (Gillich et al., ).Cited by: 6.
