摘要

摘要: 基于Jiles-Atherton模型、魏德曼效應和壓磁效應建立了考慮磁滯影響下磁致伸縮位移傳感器的輸出電壓模型,計算結果與實驗結果基本吻合,表明所建立的輸出電壓模型的正確性.對傳統Fe-Ga磁致伸縮位移傳感器的結構進行了改進,消除了由磁致伸縮材料的磁滯效應帶來的位移遲滯,降低了剩磁和驅動脈沖電流對輸出電壓的影響,使電壓信號的信噪比由14.7 dB提高至27.6 dB.制作了Fe-Ga磁致伸縮位移傳感器樣機,通過實驗驗證了新結構能改善傳感器的線性度、重復性、遲滯性和精度.基于新的傳感器結構,此研究可為磁致伸縮位移傳感器的優化、生產提供理論依據和實驗基礎.

Abstract: The output voltage computation model of a magnetostrictive displacement sensor was established considering the influence of the hysteresis effect based on the Jiles-Atherton hysteretic model, Wiedemann effect, and piezomagnetic effect. The consistency between the calculated data and experimental data shows the correctness of the output voltage model. The structure of the traditional Fe-Ga magnetostrictive displacement sensor was improved, eliminating displacement measurement hysteresis caused by the hysteresis effect of the magnetostrictive material, thereby reducing the influence of the residual magnetization and the driving pulse current on the output voltage so that the voltage signal-to-noise ratio increased from 14.7 to 27.6 dB. A type of Fe-Ca magnetostrictive displacement sensor was fabricated. The experiments show that the new structure can improve the linearity, repeatability, hysteresis, and precision of the magnetostrictive displacement sensor. Based on this new sensor structure, the research provides a theoretical and experimental basis for optimization and manufacture of magnetostrictive displacement sensors.
