| 为了研究磁控电弧焊缝跟踪传感器的电磁特性,采用ANSYS软件对传感器进行了谐波磁场分析,当线圈匝数、空气隙长度、铁心磁导率等因素分别发生改变时,得出了磁控电弧焊缝跟踪传感器的磁力线分布和磁场矢量图;分析了电弧传感器主要参数对磁场分布和磁感应强度大小的影响规律,并与采用高斯计测得的实际磁感应强度进行了对比.结果表明,采用有限元方法对磁控电弧传感器的电磁特性的分析结果与试验结果吻合,为磁控电弧焊缝跟踪技术提供了基本的理论指导. |

| Abstract: |
| In order to research the electromagnetic characteristics of the magnetic control arc welding seam tracking sensors, the harmonic magnetic field of sensor is analyzed with ANSYS software:when the coil circle number, air gap length, core magnetic conductance factors change respectively, the magnetic control arc welding seam tracking sensors magnetic maps and magnetic field vector diagram are obtained.The influence law of the main parameters of arc sensor on the magnetic field distribution and the size of the magnetic induction is analyzed, and is compared with the actual magnetic induction intensity measured by gauss plan.The results show that analysis results of using the finite element method for magnetic control arc sensor electromagnetic properties and test results are coincide.It provides theoretical guidance for magnetic control arc welding seam tracking technology. |
