基于ANSYS的磁探仪工装研制

Research and Development of Fixture of Magnetic Particle Detector Based on ANSYS

文中所研制的工装,可解决交叉磁轭磁探仪在检测弧形工件时,因提升力过大导致拖动困难的问题。文中基于有限元法,首先采用PROE软件对磁轭、工装、夹具等进行建模,再采用ANSYS MAXWELL软件对磁探仪的磁场进行模拟仿真,分析磁极端部形状的改变,对磁感应强度及磁探仪受力情况的影响。并制作实物对仿真结果进行验证,试验证明仿真结果较为可靠。工装的各项性能指标均符合NB/T47013-2015要求。

The fixture can solve the problem of dragging difficulty caused by too large lifting force when cross shaped yokes detecting arcshaped workpiece with magnetic field.Based on the finite element method,this paper first uses the PROE software to model the yoke,fixture,etc.,then uses the ANSYS Maxwell software to simulate the magnetic field of the magnetometer,and analyzes the change of the shape of the pole end,the impact on the magnetic induction strength and the force of the magnetometer.The simulation results are verified by the real object,and the test shows that the simulation results are more reliable.All performance indexes of fixture meet the requirements of NB/T47013-2015.
