摘　　要：针对铁磁材料的应力状况、疲劳寿命及硬度等力学参数的测量手段和方法，利用铁磁性材料的特性之──—ｍａｇｎｅｔｉｃ Ｂａｒｋｈａｕｓｅｎ　ｎｏｉｓｅ效应，依据磁弹噪讯理论，研究了磁弹噪讯产生的机制，并研制出磁弹噪讯传感器和相应的铁磁材料应力与疲劳损伤检测仪器．实践证明：所研制的检测仪器及检测技术具有检测速度快、检测精度高、便于携带的优点．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.
