Abstract

A mathematical model, including the circuit, electromagnetic field, thermal field and structural field, is established to study the interaction mechanisms and inherent laws of transient multi-physical fields in the launching process of an electromagnetic railgun. Some actual factors, such as material nonlinearity, structural deformation, contact and collision, are also accounted in the model. The electromagnetic and thermal fields are solved by the implicit finite element method, the structural field is solved by the explicit finite element method, and these fields are coupled by load transfer and time synchronization. Thus a transient multi-physical field solver was developed. The rationality of the calculated results is discussed by taking the launching processes of solid-armature railgun and synchronous induction coilgun as example. The results show that the launch of an electromagnetic gun is a complex dynamic process under multi-physical field coupling and multi-body interaction, in which some transient phenomena, such as current and magnetic field diffusion, temperature rise, stress propagation, contact and collision, exist. The launching performance is closely related to the structures, material properties and excitations.
