摘要
为了解决目前动态轨道衡中使用的应力传感器存在的问题,开发了一种基于非晶态合金薄带的压磁电感式应力传感器。论述了传感器的工作原理,推导出了它的输出方程,并分别在材料试验机与矿山有轨运输轨道上进行了静态特性标定和实测试验。试验显示,这种传感器具有较高的测试精度和灵敏度。另外,这种传感器结构简单、安装方便、坚固耐用,应用于动态轨道衡是可行的。
In order to solve some problem of stress sensor in dynamic weigh rail, a new kind of inductive stress sensor based on magnetostriction effect of amorphous alloy was developed. First, the principle of sen-sor,and its irrferred output equation were discussed. Second, the static characteristic experiment and the actual experiment on the material testing machine and the mine haulage rail were separately made. The results of the test have showed that this stress sensor has some characteristics as high measurement sensi-tiveness and accuracy. Also being simple, convenient and solid to install and use, so it is feasible to apply the sensor for the dynamic weigh rail.
