摘要
以研制的磨粒传感器为对象,运用电磁场原理、毕奥-萨伐尔定律等,推导出一种新型磨粒传感器的感应电动势输出模型,并以试验验证其正确性。还由此分析了传感器的线性度、灵敏度与各个参数之间的变化规律。研究结果表明,该传感器线性度较好,但是在检测磨粒尺寸少于100m时,传感器的灵敏度与线性度较差,因此还需对传感器进行线性化处理及结构参数优化,以期获得较高的灵敏度。
Taking the wearing debris sensor as the object, electromagnetic field principle and Biot-Savart Law ware utilized to establish the output model of the new type wearing debris sensor induction voltage as well as confirmed by experiment. Additionally, the change rule among the linearity, sensitivity of sensor and every parameter were analyzed. The results show that the sensor has a better linearity, but sensor＇s sensitivity and the linearity are bad while the examination abrasive size is bellow 100μm, therefore it obtains the high sensitivity by optimization the sensor with structure parameters and linear processing.
