Abstract | In this paper, circuit simulation was chosen as the main methodology for research on the characteristics of electromagnetic rail launcher (EML or railgun) system. Nevertheless, the simulation model was not merely built on the static electrical characteristics. Moreover, practical physical processes contributed to the system have also been taken into consideration and expressed as electric parameters. Thus the description of a relatively complex system could be realized by a comparatively simple manner, and the simulation result is more accurate and reliable compared with the traditional circuit simulation ones with static electrical characteristics. A circuit simulation model of an EML system based on PSpice software was built, in consideration of multi-field characteristics, such as current skin effect, contact pressure and contact resistance on the contact surface of the armature and the barrel, velocity skin effect, friction drag and temperature coefficient of electrical resistivity. Simulations were made based on the improved complex model. Last but not least, comparison between the simulation results and the experimental ones was made to verify the accuracy and effectivity of the improved model. |

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.
