In order to analysis the distribution characteristics of in-bore magnetic field for C-shaped armature electromagnetic railgun. a computational model considering dynamic contact pressure is established. By solving the dynamic equation. the in-bore motion characteristics of the armature are obtained. https://www.diegojavierfares.com/amazing-price-Rubbermaid-8-Gallon-Plastic-Home-Office-Wastebasket-Trash-Can-with-Liner-Lock-p12316-big-deal/
