Aimed at the measuring means and methods of mechanical parameters, such as stress, fatigue life, and hardness of ferromagnetic materials, this paper applies one of the properties of ferromagnetic materials, that is, magnetic Barkhausen noise effect, and adopts magneto-elasticity noise theory in the research into the mechanism for the generation of magneto-elasticity noise. Thus, a magneto-elasticity noise sensor and a relative detector for the stress of ferromagnetic materials and fatigue damage are developed, which is of high speed, high accuracy, and is easy to carry.
