Abstract

In modern structure

ferromagnetic steel material is widely used as bearing structure

the stress state directly related to the safety of the whole structure.Because the influences of stress on steel materials magnetic characteristic parameters is obvious

the basic principle is analyzed and a sleeve type electromagnetic stress sensor is designed.Using the finite element simulation technology FLUX software to test the rationality

and the design combining the experiment and simulation is put forward

the output voltage of sensor is calibrated.Through the contrast of the experiment and simulation results

the correctness of the method is verified for the stress testing sensor and provides a high efficient calibration approach to make it more valuable in the market.
