A novel bulk magnetostrictive sensor for bending applications
Source abstract
Abstract
In this paper, a bulk magnetostrictive material is used to measure bending forces. It is made of a cylindrical vanadium permendur alloy. In this sensor, two comb shape magnetic cores and excitation coils are used to create magnetic fields in the material’s surface layer. When bending force is applied to the material, created stresses causes a change in the magnetic flux density on the surface of the material. Induced voltage changes in the pickup coils are used as the output of the sensor. The range of the sensor is up to 280 Newtons. The accuracy of the bending sensor is ± 5.1 % F S . The bending force measurement sensitivity of the sensor is 7.5 m V / N . By performing combined loading tests, it was found that the sensor is able to detect bending force in both directions. The outputs of the two directions are decoupled and only 4.7 % is affected by each other.
