基于磁偶极子的矿用钢丝绳疲劳定量分析

摘要

矿用钢丝绳的疲劳损伤主要是断丝，为了能够定量判断矿用钢丝绳的损伤强度，运用电流环磁偶极子作为理论模型，根据磁记忆检测理论推导出了钢丝绳损伤区域磁场分布，得出了矿用钢丝绳疲劳裂纹各个参数对金属磁记忆信号的影响。%The primary fatigue damage of mining steel rope is wire breaking. Circuit and magnetic dipole as a theoretical model, magnetic memory is used to induce the magnetic field distribution of the damage zone in order to quantitatively assess the damage strength of the mining steel rope. On the metal magnetic memory signals, the effect of the fatigue crack parameters of the steel rope was obtained.
