中文摘要：
依据金属磁记忆检测的基本原理,提出关于齿轮早期局部微裂纹缺陷的漏磁信号模型,指出在裂纹区域,漏磁场的切向分量具有峰值,而法向分量过零、其梯度具有峰值,分析了裂纹深度对上述特征的影响,并将上述理论应用于实际齿轮表面微裂纹检测,显微分析的结果论证了磁记忆检测的有效性。
英文摘要：
Based on basic principle of metal magnetic memory（MMM）,this paper proposes a model of magnetic flux leakage signal of gear early local micro cracks.The tangential component of magnetic flux leakage signal will peak at the crack area while the normal component will pass zero point and its gradient has the peak.The effect of the crack depth on the characteristics has also been considered.The theory is then applied to detection of micro cracks on the tooth surface of an actual gear.The microscopic analysis results demonstrate the effectiveness of the magnetic memory testing.
