摘　　要：针对现有锚杆轴力检测方法存在的不足,利用非晶态合金薄带压磁效应,根据感应线圈输出电压大小判断锚杆轴力大小,阐述了该传感器的结构和原理。搭建传感器测试系统,分析了气隙大小、励磁电压幅值和励磁频率对传感器输出特性的影响,并对传感器进行了静态特性标定。In view of the existing deficiencies of the existing method for detecting the axial force of anchor bolt,the magnetic force effect of the amorphous alloy thin strip was used to determine the axial force of the anchor bolt based on the output voltage of the induction coil.The structure and principle of the sensor were explained.A sensor test system was set up to analyze the effects of air gap size,excitation voltage amplitude,and excitation frequency on the output characteristics of the sensor,and the static characteristics of the sensor were calibrated.

关 键 词：锚杆轴力传感器 非晶态合金薄带 压磁效应 静态特性
