摘要

本文对45#钢带圆孔试样的应力及其与磁信号的相关性进行了有限元分析。得到了试样在不同载荷作用下的漏磁场信号。结果表明:拉应力越大，圆孔上方2mm处的应力越大，渗透率随应力的增大先增大后减小;漏磁信号与磁导率相关，漏磁信号的切向分量呈先增大后减小的趋势。漏磁场信号的法向分量出现过零现象。

Finite element analysis of magnetomechanical coupling behaviour of perforated steel plate

In this paper, finite element analysis is carried out for the stress of a 45# steel specimen with a round hole and its correlation with a magnetic signal. The leakage magnetic field signals of the specimen under different loads are obtained. The results show that the greater the tensile stress is, the greater the stress is at 2 mm above the round hole, and the permeability first increases and then decreases with the increase in stress. The leakage magnetic field signal is correlated with permeability and the tangential component of the magnetic flux leakage signal has a trend of increasing first and then decreasing. The phenomenon of zero crossing of the normal component of the leakage magnetic field signal appears.
