Abstract | Give the fact that the double-deck rail demonstrates excellent performance in preventing rails melting and gouging during EML tests, theory and simulation research was carried out on the lateral vibration of the double-deck rail and contact properties between the armature and the rail in this paper. We deduced the lateral vibration contact equations of the double-deck rail by simplifying electromagnetic rail launcher as Bernoulli-Euler model based on the elastic foundation. A finite element code was used to help us model the launch progress. Influence of the double-deck rail scheme and rail height ratio was also analyzed. Both the characteristics of the contact surface between the rail and the armature and the displacement of the armature were considered. The results show that the double-deck rail can inhibit the propagation of bending waves and efficiently reduce rail gouging, beside, the double-deck rail height ratio has much influence on this effect. |

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.
