摘要:

桥式极化磁系统电磁继电器具有体积小、重量轻、灵敏度高等优点,但实际生产中出现的衔铁位置偏移问题对吸力与反力产生影响,不利于继电器电寿命的提升。首先建立电磁继电器的虚拟样机模型,通过电磁系统与触簧系统仿真模型实现继电器吸力和反力的静态特性仿真。然后基于实测衔铁位置偏移量,通过解析与仿真,研究衔铁位置偏移时电磁吸力与反力的变化过程。最后基于吸反力特性配合,分析衔铁位置偏移对继电器吸合电压、释放电压及电寿命产生的影响,为严格控制衔铁与小轴的点焊能量,避免出现衔铁位置偏移的要求提供理论依据。

Abstract:

The electromagnetic relay with the bridge-type polarized magnetic system has the advantages of small size,light weight and high sensitivity.However,the armature position deviation in actual production affects the electromagnetic force and spring force,which is not conductive to the improvement of the electrical life of the relay.Firstly,the virtual prototype model of the electromagnetic relay with the bridge polarized magnetic system is established,and the static characteristics of the electromagnetic force and spring force of the relay are simulated through electromagnetic system and contact spring system simulation model.Secondly,based on the measured armature position offsets,the process of electromagnetic force and spring force are investigated when there is armature position deviation by the theoretical analysis and simulation.Finally,the influence of different armature position offsets on pull-in voltage,release voltage and electrical life of relay are analyzed according to the cooperation between electromagnetic force and spring force.The above investigation provides the theoretical foundation for the demand of strictly controlling the spot-welding energy of armature and small axis for avoiding the armature position deviation.

Key words: bridge polarized magnetic system, relay, virtual prototype, pull-in voltage, release voltage
