铁基非晶合金整体磁芯轴向拉压型测力传感器的研究与设计
Research and Desing on a Axial Tensile and Compression Force Sensor With a Fe-base Amorphous Alloy Magnetic Core
摘要
Abstract
By wrapping Fe-based amorphous alloy strip into a cylindrical stress-sensitive magnetic a force sensor was made based on magneto-elastic effect,it can measure the tension,but also to measure the compression.The principle and structure of the sensor were presented,and its output characteristic equation was derived.By making a tensile and compression measuring experiment,the best excitation magnetic field strength,static characteristics and temperature characteristics of the sensor were analyzed.The experimental result shows when the sensor measure tensile and compression force,its the maximum linearity error is respectively 0.41％ F.S and1.12％ F.S,repetitive error 0.86％ F.S and 0.85％ F.S,and the average sensitivity is respectively 0.71 mV/kN and 1.16 mV/kN.关键词
