| Abstract | Contact wire is one of the most important components used to supply electricity to railway vehicles which equipped with a pantograph. When the speed of electric vehicle is not as high as now, the failure of contact wire caused by friction and wear behaviors of carbon strip/contact wire were considered more important. But the fatigue fracture become more and more important for the failure of contact wires on account of several fatigue fractures happened while the speed of electric vehicle increase continuously. A bending fatigue tester simulating the working conditions of contact wires developed by Kang and etc has been used to evaluate the fatigue characteristic of pure copper and Cu-Sn alloy contact wires. In this study, this bending fatigue tester also is used to evaluate the fatigue characteristics of Cu-Mg alloy contact wire which developed for 400km/h high speed rail in Korea. Test result is also compared with the result of Kang’s research on pure copper contact wire. Finally, in order to evaluate the fatigue life of contact wires for any mean stress, the relationships between plastic strain and fatigue life were abstained for two kinds of contact wires combined the FE analysis. |

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.
