Coupling Sensor-Based Structural Health Monitoring with Finite Element Model Updating for Probabilistic Lifetime Estimation of Wind Energy Converter Structures
نویسنده
چکیده
The worldwide demand for green energy systems is evident. In this context, wind energy converters will play a paramount role. Extending the service life of a wind energy converter translates into significant economic savings as well as ecological earnings. New opportunities for the management and operation of the wind energy converters make it beneficial to know the structural condition and the remaining life span of wind energy converters at each point in time during their operation. This paper presents the implementation of an integrated framework for probabilistic lifetime estimation of wind energy converter structures coupling sensor-based structural health monitoring with finite element model updating.

متن کاملA NEW APPROACH BASED ON FINITE ELEMENT MODEL UPDATING FOR STRUCTURAL DAMAGE IDENTIFICATION
In this study, the finite element model updating was simulated by reducing the stiffness of the members. Due to lack of access to the experimental results, the data obtained from an analytical model were used in the proposed structural damage scenarios. The updating parameters for the studied structures were defined as a reduction coefficient applied to the stiffness of the members. Parameter v...
