一种基于ANSYS的磁控电弧焊缝跟踪传感器热-磁耦合分析方法

thermal- magnetic coupled-field way of analysis of magnetism-control arc seam tracking sensor based on ANSYS is put forward in this thesis to study the thermal influence on magnetism in the sensor working process. In the first place, a general review is provided on the magnetism-control arc seam tracking system and sensor. Then, a thermal- magnetic coupled-field physical modal of magnetism-control arc seam tracking sensor is built in the finite element method. A analysis and calculation of the thermal field is then made in ANSYS; based on the results, the magnetic-field is analysis and calculated. Then a method of experimental verification and modal modification is presented respectively of thermal-field and magnetic-field analysis. This thesis put forward the coefficient αΒ, indicating the thermal-influence on magnetism of magnetism-control arc seam tracking sensor. The comparison between the simulating result with the actual result shows that the two results match. This way is feasible in analyzing magnetism-control arc seam tracking sensor.
