Problems solved by technology

[0003] Most of the existing realization devices are realized by putting the metal wire into the solenoid. When the length of the metal wire changes during the experiment, the positions of the two ends of the metal wire will change, so that the metal wire is in the position of the solenoid. The position changes, which will affect the experimental results. Therefore, we propose a magnetostrictive micro-deformation measurement experimental device

Abstract

The invention discloses a magnetostriction tiny deformation quantity measurement experiment device, and relates to the field of magnetostriction variable measurement equipment, the magnetostriction tiny deformation quantity measurement experiment device comprises a mounting seat, the side part of the mounting seat is provided with a scale and a fixed optical reflector, the side part of the mounting seat is provided with a power supply, and the top part of the mounting seat is provided with a solenoid and a fixed block. During use, one end of a metal wire is firstly placed in the fixing hole in the fixing block, one end of the metal wire can be fixed through the fixing mechanism, then the metal wire penetrates through the fixing holes in the solenoid and the sliding block, and the other end of the metal wire can be fixed through the fixing mechanism. Then the solenoid can be powered on for detection through the power supply, the metal wire does not deviate during detection and is always located on the central axis of the solenoid, the detection precision can be improved conveniently, and meanwhile switching can be conducted through the elastic switching mechanism; therefore, when the contracted metal wire is measured, the measurement of the metal wire is not affected by the elastic switching mechanism.

Description

technical field [0001] The invention relates to the field of magnetostrictive variable measuring equipment, in particular to an experimental device for measuring magnetostrictive small deformation. Background technique [0002] Magnetostriction is a ferromagnetic substance (magnetic material) whose size changes with the increase of the magnetization intensity due to the change of the magnetization state. The size of the ferromagnetic substance is elongated (or shortened) under the action of an external magnetic field. After the external magnetic field is removed, It returns to its original length again, a phenomenon known as magnetostriction (or effect). [0003] Most of the existing realization devices are realized by putting the metal wire into the solenoid. When the length of the metal wire changes during the experiment, the positions of the two ends of the metal wire will change, so that the metal wire is in the position of the solenoid. The position changes, which will...
