Abstract

The invention provides a device for measuring the output displacement of a magnetostrictive actuator. The device comprises a laser position adjusting device, a high-speed laser displacement sensor, a power supply, a digital display and the magnetostrictive actuator. The device for measuring the output displacement of the magnetostrictive actuator has the outstanding characteristics as follows: non-contact high-precision measurement of the output displacement of the magnetostrictive actuator can be realized; longitudinal positions of laser points emitted by the high-speed laser displacement sensor are adjusted precisely through adjustment of the longitudinal position of a longitudinal slider in the laser position adjusting device; horizontal positions of laser points emitted by the high-speed laser displacement sensor are adjusted precisely through adjustment of the horizontal position of a horizontal slider in the laser position adjusting device; influence of vibration generated in a displacement outputting process of the magnetostrictive actuator and vibration generated in the external environment on the measurement precision is eliminated effectively.

Description

technical field [0001] A device for measuring the output displacement of a magnetostrictive actuator belongs to the field of displacement measurement of magnetostrictive actuators, in particular to a measuring magnetostrictive device that uses a high-speed laser displacement sensor as a displacement measurement element and uses a laser position adjustment device to realize measurement position adjustment. A device that outputs displacement from an actuator. Background technique [0002] Magnetostrictive materials are another new type of rare earth functional materials emerging after rare earth permanent magnets, rare earth luminescence, and rare earth high temperature superconducting materials. Magnetostrictive effect is one of the important physical effects of magnetostrictive materials. The magnetostrictive effect refers to the phenomenon that the length and volume of ferromagnetic materials and ferrimagnetic materials will change slightly due to the change of magnetizati...
