    摘 要:双线圈电磁继电器的电磁系统是电能和机械能相互转换的媒介,为实现更理想的能量转换和分布效果,需要模拟和分析磁场能量的分布情况。结合三维建模软件和电磁场有限元分析软件,对双线圈继电器进行仿真研究,测试中测量装置采用柔性协作机器人和三轴高斯计,用相应的模具固定继电器。编写控制机械臂的脚本程序,使其带动高斯计围绕被测继电器按照指定路径运动,实时采集位置信息和磁场信息,实现路径坐标系和绘图坐标系的虚实合一,将机械臂仿真及运行路径的坐标系和上位机空间磁场强度分布绘图坐标系实现坐标一一对应,测量出继电器三维矢量磁场强度。对比仿真得到的磁感应强度数据与测量得到的数据,验证了仿真计算的真实可靠性。

    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
