Abstract
The present invention provides a modeling simulation and multi-field coupling analysis method for electromagnetic railgun system, comprising: for electromagnetic railgun, respectively building mathematical model of pulse shaping unit, mathematical model of armature impedance, mathematical model of rail and dynamic model of armature of electromagnetic railgun system; by using modularization method, forming simulation model of the electromagnetic railgun based on each built model; carrying out coupling simulation on current density and magnetic induction intensity distribution of the simulation model of the electromagnetic railgun, and analyzing coupling action and distribution characteristics of electromagnetic field in launching process of the electromagnetic railgun and influence of the electromagnetic field on temperature field distribution; based on the analysis result, determining positions where severe ablation appeared and electric contact arcing easily generated on the electromagnetic railgun, and carrying out preventive and maintenance measures.
