| Abstract | For the improvement of reliability, safety and efficiency advanced methods of supervision, fault detection and fault diagnosis become increasingly important for many technical processes. To determine the condition of an inaccessible fault in an operating mechanical system, the vibration signal of the machine is continuously monitored by placing sensors close to the source of the vibrations. These signals are further processed to extract the features and identify the status of the machine. This paper deals with a new scheme for the detection and diagnosis of localized defects in machine rotating components based on Self Adaptive Growing Neural Network (SAGNN) classifier which is a novel approach to pattern classification propounded for tackling fault diagnosis tasks. Feature vector is extracted from signal in time domain and SAGNN is trained and used as a diagnosis classifier. In order to evaluate SAGNN, the data sets obtained from vibration signals are classified with both SAGNN and Radial Basis Function (RBF) classifiers. The proposed algorithm is applied to the fault diagnosis of mechanical rotary machine, and the test results show that classification by mean of SAGNN identify the faults of rotary elements (Gears, bearing and belts) more accurately and has better diagnosis performance compared to the RBF. |

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.
