title = "Analysis of Release Voltage Fluctuation Mechanism of Electromagnetic Relay with Bridge Polarized Magnetic System",
abstract = "The electromagnetic relay with bridge polarized magnetic system is widely used in the aerospace field due to its advantages of small size and high sensitivity, but the release voltage fluctuation problem in the whole relay assembly greatly reduces the assembly qualification rate of its products. This paper firstly determines the key assembly procedure corresponding to the release voltage fluctuation of the electromagnetic relay with the bridge polarized magnetic system. The simulation models of the electromagnetic system and reed system have been established. On this foundation, the simulation results verify the presence of magnetic flux leakage in the relay shell, which has effect on the main magnetic flux and the axial electromagnetic force applied on the armature. Then the paper calculates the axial electromagnetic force applied on the armature with and without the relay shell at each armature angle under the rated voltage in order to analyze the influence of the axial electromagnetic force on armature position. Through simulation, the changes of electromagnetic torque and reed torque before and after the change of armature position are obtained, which is used to determine the determinant of the reduction of release voltage before and after relay multiple operations at normal temperature. These analysis results of the release voltage mechanism lay a theoretical foundation for improving the qualified rate of relay assembly.",
