基于电磁法的DC01钢应力检测研究
|
摘要
针对铁磁性材料受到应力作用导致失效的问题,采用巴克豪森噪声(MBN)法评估DC01钢的受力情况。应力的加载改变了铁磁性材料内部微观结构,从能量角度出发,结合磁畴理论及磁化理论,在微观层面定性分析了MBN信号变化的原因,定量分析材料在屈服强度变化范围内静载拉伸应力与MBN信号的对应关系。
Aiming at the failure of ferromagnetic materials due to stress,magnetic Barkhausen noise( MBN) method was used to evaluate DC01 steel. Loading stress changes the internal micro-structure of ferromagnetic material. Combined with the magnetic domain theory and magnetization theory,the causes of MBN signal change are qualitatively analyzed at microscopic level from the energy view,then the article quantitatively analyzes the correspondence between static tensile stress and MBN signal in the range of yield strength variation.
