| Abstract | Blades are the key components of large scale wind turbine. It is significant to do the detection and damage diagnosis for it. However, the changing circumstance and variable load always make the blade’s vibration signal complex. To detect damage information of blade, some dyn parameters are picked up from the signal measured and used as the characteristic. In this paper, a dynamics model of 300w wind turbine has been build in FEM. Via modal analysis and dynamics emulate, obtain dyn properties, get the characteristic frequency¿vibration shape and response data. Apply the theory of length fractal dimension on nonlinear vibration system to calculate the length fractal dimension in the blade’s normal or damaged situation. The dimension can be used as the surveying characteristic to do the diagnosis. The method presented in this paper provides an academic reference and an example to research the detection and damage diagnosis further for large scale wind turbine blades. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
