摘要
基于电磁检测原理,探讨了一种适合于检测工作在煤矿井下的液压支架的活塞杆伸缩距离的电磁检测新方法.此方法也同样适合于地面机械设备运动构件移动距离的在线定量检测.
On the basis of the theory of electromagnetic test the paper researchs a new electromagnetic testing method which is not only fit for testing the distance of stretch out and draw back of the piston rod of hydraulic support working under the mining pit but also for the linear constants of the mechanical equipments working on the ground
