Abstract | The Principal Component Analysis (PCA) has been widely used to detect and diagnose the faults of industry processes. However, this technique is rarely applied to the fault detection and diagnosis of rolling element bearing. The main reason is that PCA is a kind of multivariate statistical technology, but bearing vibration signal is one dimensional time series. A new method of fault detection based on PCA for rolling element bearing is proposed in this paper. Firstly, the vibration signal is mapped into a high dimensional space. Then, PCA is applied in this space. The proposed method is tested with experimental data collected from drive end ball bearing of a 2 hp Reliance Electric motor driven mechanical system. The simulation results show the PCA-based method of bearing fault detection is effective and is superior to the traditional PCA-based approach. |

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.
