摘要

摘要: 通過對Q235鋼退磁試件的拉伸、壓縮試驗,利用磁記憶在線監測系統實時跟蹤記錄了不同拉壓應力作用下試件表面的磁信號變化特征. 結果表明:拉伸載荷對合成磁場的影響是先減小后增加的,在接近材料屈服強度的0.3倍左右后趨于穩定不變;而壓應力引起的合成磁場初期快速下降,之后處于上下波動變化. 通過引入拉壓應力所產生的不同應力退磁項,對J-A磁機械效應模型進行了改進,模擬結果與試驗數據具有較好的的一致性,可用于拉壓不同應力致磁機理的理論解釋.

Abstract: The tensile and compressive stresses of demagnetized specimens made of Q235 steel were tested, and magnetic signal variation characteristics under different tensile and compressive stresses were continuously recorded using a magnetic memory on-line monitoring system. The results demonstrate that the resultant magnetic field first decreases and then increases induced by tensile load and becomes stable when approaching and exceeding 0.3 times the yielding strength of the material, while the resultant magnetic field induced by compressive stress rapidly decreases in the initial stage and then fluctuates. The model for J-A magnetomechanical effect was improved by introducing different stress demagnetization terms caused by tensile and compressive stresses, and the simulation results are consistent with the experimental data, which can be used for theoretically explaining different mechanisms induced by tensile and compressive stresses.
