| Abstract | During the past few decades, various calculation models have been introduced into studying solid armature railgun. In this paper,four models, including constant resistance model, speed resistance model, current resistance model and multi-factor resistance model, were studied in detail. To verify their validity, experimental and simulation methods were adopted in both low and high velocity cases. By conducting a 3-D eddy current electromagnetic field simulation with the finite-element numerical method, self-inductance gradient (Lr′) is got. The control equations of these different resistance models can be solved by the Runge-Kutta method. Comparisons of experimental and simulation results of these different resistance methods indicate that friction coefficient resistance model can describe armature resistance during the movement process of solid armature and improve the accuracy of simulation analysis in both low and high velocity cases. |

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.
