为提高测力传感器的测量精度和灵敏度,研制了一种以非晶态合金材料为压磁元件的测力传感器.首先,对硅钢片、坡莫合金以及铁基非晶态合金的软磁特性进行了比较,选择了国产Fe_(80)B_(20)辊剪薄带作为传感器铁芯冲片.其次,通过对传感器的磁路分析,推导出了它的感应输出方程.然后,根据铁磁学和现有参考资料,确定了传感器的各项技术参数.最后,对传感器的静态特性以及励磁电流强度、励磁频率的影响进行了试验研究.试验结果显示,非晶态合金压磁测力传感器比硅钢片、坡莫合金等晶态合金压磁传感器有更高的精度和灵敏度以及更宽的频率响应范围.

In order to improve the measuring accuracy and the sensitivity of the force sensor, a new kind of the magnetoelasticity force sensor was developed, which takes the amorphous alloy material as its iron core. Firstly, the comparison was made about the soft magnetism characteristic of the silicon steel sheet,the perm alloy as well as Fe-base amorphous alloy , and the domestically produced roller-cut Fe_(80)B_(20) thin belt was chosen to as the sensor ferrite core. Secondly, through analysis of sensor magnetic circuit, the sensor output equation was derived, and according to the ferromagnetism and the presented references, the sensor technical parameter was determined. Finally, the experimental was made on the sensor static characteristic as well as the exciting current intensity, the excitation fre-quency influence on its output performance. The experimental results show that this kind of force sensor is much higher than those based on the silicon steel sheet and the penn alloy in the measuring accuracy and the sensitivity, and it also has more broad frequency response scope.
