According to the magnetic Barkhausen noise effect and the magnetic bomber noise theory, the measurement methods and methods of the mechanical parameters such as the stress state, the fatigue life and the hardness of the ferromagnetic material are studied. The mechanism, and developed a magnetic bomber noise sensor and the corresponding ferromagnetic material stress and fatigue damage detection equipment. Practice has proved that: the development of testing instruments and testing technology has the advantages of fast detection, high detection accuracy, easy to carry.
