磁记忆切向分量信号的检测试验

针对金属磁记忆切向信号检测方向难以确定的问题，提出同时检测切向平面上相互垂直的两个切向分量，采用矢量合成法进行合成，进而得到金属磁记忆最大切向分量的方法，并用ANSYS仿真对该分量的有效性进行验证。通过铁磁性金属构件拉伸试验对磁记忆切向分量信号与应力集中部位和应力集中程度的关系进行研究，并对磁记忆切向分量信号的K曲线进行分析。结果表明，采用矢量合成法合成的金属磁记忆切向分量信号可以作为金属磁记忆最大切向分量，能直观和准确地反映应力集中部位和应力集中程度。

Testing and Analysis of Tangential Component Signals of Metal Magnetic Memory

The method of resultant vector was adopted to extract tangential component signals of metal magnetic memory due to the problem that the tangential component signals of metal magnetic memory is very hard to be extracted, and its validity was verified by the use of ANSYS simulation.The relationship between tangential component signals of magnetic memory with stress concentration position and stress concentration degrees was investigated untler static tension conditions testing,and the K curve of tangential component signals of magnetic memory was analyzed.The result shows that the tangential component signals of metal magnetic memory can be effectively extracted by the method of resultant vector,and the stress concentration positions and stress concentration degrees can he reflected intuitively and accurately by tangential component signals of metal magnetic memory.
