Application of Lissajous Figure in Two-dimensional Magnetic Memory Detection
Zhen Wang · Acta Aeronautica Et Astronautica Sinica · 2013
In the paper,the theory of two-dimensional magnetic memory testing is employed.The zero point in the normal component and the maximum point in the tangential component are together adopted for detection.Lissajous figure analysis is introduced.The Lissajous figure of synthesis for the normal and tangential components and the Lissajous figure of synthesis for the differential value of the normal component and the tangential component are used for analysis.It turns out that the area of the Lissajous figure of synthesis for the differential value of the normal and the tangential components can be used to determine the degree of stress concentration,and it is concluded that in different stress concentration degrees,the order of magnitude of the Lissajous figure area can be used as a threshold.This study can provide a test analysis basis for further research on the quantitative analysis of two-dimensional detection of magnetic memory by using the Lissajous figure analysis method.
