## Abstract

Diverse approaches to HFCG's inductance,resistance and armature expansion calculating are evaluated. Comparison of simulated and experimentally obtained results is provided. Validity criteria for different simulation models are proposed. Consideration of armature acceleration under the pressure of detonation products is shown to be beneficial for accuracy of HFCG simulation. Control of HFCG temperature during simulation enables detecting critical points of system operation.
