A model of electromagnetic launcher under non-ideal conditions is established based on the theory of impact dynamics and practical engineering considerations. Numerical simulation is conducted using specialized software to investigate the mechanical properties and gouging characteristics of rail-armature contact during electromagnetic launch under non-ideal conditions. Through numerical computations, distributions of current density, Lorentz force, and stress on the rail/armature interface are obtained. The study explores the gouging characteristics under different conditions, revealing that the non-steady motion of the armature results in high-speed collisions, which are the primary cause of rail gouging. By analyzing the gouging characteristics of electromagnetic launcher under non-ideal conditions, this study provides a basis for further efforts to suppress rail gouging phenomena.
