Abstract :
The magnetostrictive position sensor is a kind of displacement sensor utilizing the magnetostrictive effect and inverse effect of magnetostrictive material. This essay discussed the distribution characteristic of the magnetostrictive position sensor under the impulse magnetic field. We analyzed the impulse magnetic field of magnetostrictive line influenced by the magnetic field of permanent magnet and the impulse current magnetic field, and constructed relative theory models. Applying the numerical simulation software ANSYS, the impulse magnetic field on the sensor line was emulated based on electromagnetic theories. With experiment data, the values of magnetic field and magnetic field direction angle in magnetostrictive line were calculated. Consequently, this essay should provide the theory basis and data for promoting the signal quality of the signal detection of the sensor.
