Design and fabrication of an electromagnetic stress sensor

摘要：

Ferromagnetic steel material is widely used as the bearing carrier in structure, whose stress would influence the entire security. As stress has a notable influence on magnetic characteristic parameters of steel material, with analysis of basic principles, a tubular type magnetic stress sensor is proposed in this paper. We verified the rationality of the magnetic path design with finite element analysis (In FLUX), and proposed a method combined with experiment and simulation to calibrate the output voltage of the sensor. With the comparison of the simulation and experimental results, feasibility of this means is proved, providing a high efficient calibration method of this kind of stress detection sensor, showing a promising marketing value.
