电磁轨道炮纤维缠绕身管多物理场耦合仿真研究OA

To investigate the performance of the launching device during electromagnetic launch,this study analyzes the multi-physics coupling characteristics during launch by combining theoretical derivation and finite element simulation.Taking the filament-wrapped barrel of a series-augmented electromagnetic railgun as the research object,the ACP module was used to model the composite material layup of the filament-wrapped barrel constraint structure,establishing an effective mesh model of the constraint structure.Through a segmented coupling method,the position of the armature in the electromagnetic field at different times was manually adjusted.The simulation results of the electromagnetic field in different segments were used as load sources for the thermal and structural fields,enabling multi-physics coupling simulation of the electromagnetic railgun barrel.The distributions of electromagnetic,thermal,and structural field characteristics across various components of the barrel were obtained,providing theoretical support for the subsequent optimized design of electromagnetic railgun barrels.
