ANALYSIS AND SIMULATION OF THE WIND TURBINE BLADES PERFORMANCE USING NONCONVENTIONAL TESTING TECHNIQUES

Abstract

The wind turbine blades are components subjected to severe loadings during its service. In this paper were implemented accelerated testing methods to assess the lifespan of products used in the renewable energy industry. This testing instrument is more and more often used by large companies that want as high quality products in as short time possible. Within these types of tests, a special emphasis is put on the accelerated testing techniques. The test laboratories that have modern test equipments and highly qualified personnel is developed more and more. Through blade’s failure cycles simulation using Monte Carlo method was determined and graphically represented the reliability indicators. At the finite element analysis for the wind turbine blade were shown the failing mode and the lifespan of the blade using accelerated stresses.
