The break arc simulation model for aerospace relay is built based on the magneto-hydrodynamics (MHD) theory. contact erosion considered and electrical conductivey of plasma sheath in root region equalized this model. static characteristics with silver vaper nitrigen are acquired computational fluid dynamics (CFD) software FLUENT. effect vapor temperature voltage analysed. Experiment results accordance results, which prove rationality validity .
