| Abstract: | On the basis of magnetic memory effect,the stress concentration detection principle was illustrated.According to the characteristic that magnetic sensor output signal was very weak,the hardware circuit including the FF2 amplifier circuit was designed and the corresponding detective software based on object-oriented programming technology was developed centered on Notebook computer.According to the function of parallel port,the specific data collection program was designed.Tensile and fatigue tests showed that this detector can effectively detect Che stress concentration of ferromagnetic component. |
