        Abstract: The electromagnetic system of the dual-coil electromagnetic relay is the medium for the mutual conversion of electrical energy and mechanical energy, and in order to achieve a more ideal energy conversion and distribution effect, it is necessary to simulate and analyze the distribution of magnetic field energy. In this paper, the three-dimensional modeling software and electromagnetic field finite element analysis software are combined to simulate the dual-coil relay, and the measuring device adopts a flexible collaborative robot and a three-axis Gaussmeter to fix the relay with the corresponding mold. Write a script program to control the robotic arm so that it drives the Gaussmeter to move around the relay under test according to the specified path, collect realtime position information and magnetic field information, realize the virtual and real integration of path coordinate system and drawing coordinate system, make the coordinate system of the simulation and operating path of the robot arm and the coordinate system of the spatial magnetic field strength distribution drawing of the host computer are corresponded to each other, and then three-dimensional vector magnetic field strength of the relay is measured. The magnetic induction intensity data obtained by simulation and the measured data are compared to verify the authenticity and reliability of the simulation calculation.
        Key words: electromagnetic relay; dual-coil; finite element analysis; vector magnetic field measurement
