Three techniques for, namely, mechanical behavior testing, failure mechanisms identification and reliability testing in accordance with different international standards of wind turbines are developed. In this project, wind turbines are subjected to static testing, dynamical testing, fatigue testing, nondestructive testing and reliability assessment in two years. The goal of this study is to obtain testing-platforms and testing procedures for reliability and quality assurances of the wind turbines. The project will work closely with other projects to achieve this goal. The research work will be conducted in two years and the research contents for each year are listed as following: (i) The 1st year Objective: Develop testing-platforms and identify failure mechanisms of specimens. Content: (a) Develop experimental fixture and apparatus. (b) Find structural properties, strength and S-N curve to support other two sub-projects. (c) Determine failure strengths of wind turbine components. (d) Use the nondestructive testing to identify the failure mechanisms of specimens. (ii) The 2rd year Objective: Assess reliability and safety of wind turbines, and establish procedure of reliability testing Content: Use the techniques developed in the previous year to achieve the following tasks: (a) Evaluate reliability of the wind turbines by performing fatigue tests and determine fatigue life. (b) Verify the correctness of the design method and the fabrication procedure. (c) Perform stain testing, vibration testing, noise testing and functional testing of wind turbines. The results support other projects. (d) Establish procedure of reliability testing of wind turbines.
