Abstract
The mathematical model of the micro electromagnetic relay is established based on the lagrange-maxwell equations. The collision effect is introduced according to the characteristics of micro electromagnetic relay to improve mathematical model. The simulation analysis indciated that the improved mathematical model is more suitable to the actual working satuts. The infections to the micro electromagnetic relay such as pick-up time, release time and velocity of armature is studied with different driving voltage and different elastic coefficient.
