摘要：
As the key part of electromagnetic railgun, the geometry structure of armature deeply affact the lunch performance of railgun. During the lunch progress, high current transmit the interface of armature and rail, and the high temperature could make the metal melt, then affact the contact performance. In this paper, Based on the function decomposition of armature, the parameterized model of the typical C type armature was established, emphasis on the ordinary C type armature and saddle C type armature, the electromagnetic-temperature-structure field coupling analysis was simulated by using FEM software Ansys, and the dynamic launching test was carried out on the launcher. The test results verify the validity of the simulation analysis, and provides technical support for the armature design. The research results in this paper have important reference value for the design and test of solid C armature. © 2020, Electrical Technology Press Co. Ltd. All right reserved.
