Numerical simulation of explosive magnetic cumulative generator EMG-720

In the present paper there are discussed the methods and results of the numerical simulations used in the development of a helical-coaxial explosive magnetic cumulative generator (EMG) with the stator diameter of up to 720 mm. In the process of designing separate units. were numerically modeled, as well as the generator operation with a constant inductive-ohmic load. The 2-D processes of the armature acceleration by the explosion products were modeled as well as those of the formation of the sliding high-current contact between the armature and stator´s insulated turns. The problem of the armature integrity in the region of the detonation waves collision was numerically analyzed.
