| 摘 要： | 通过对Q235钢拉压杆试件施加不同的应力,研究应力对其磁滞回线影响的变化规律。试验表明,随着拉应力的增加,Q235钢拉杆起始磁导率不断变大,这一阶段应力对其磁滞回线影响明显;随着磁化加大,达到磁饱和后,磁畴大部分翻转完毕,应力对其磁导率变化影响不大。Q235钢压杆随压应力增大,起始磁导率减小,这一阶段应力对其磁滞回线影响明显;随着磁化加大,达到磁饱和后,应力对其磁化影响规律不明显。用磁畴及磁畴翻转理论对试验现象进行了解释,并编制了有限元程序对试验结果进行模拟,模拟结果与试验结果吻合较好。

| Abstract: | Experimental measurements of magnetization curve and magnetic hysteresis loops changes induced by applying external stress for Q235 steel rods are presentedThe experimental results show that Q235 steel rods tend to increase their initial permeability under a tensile stress and decrease it under compressive stress,while magnetization arrived the level of saturation,the effects of the stresses on the magnetization curve became unnoticeableThe magnetization process is explained in terms of two related phenomena,domain wall and domain wall rotation of magnetizationSimulations of this influence of stresses on the major hysteresis curves are given and the simulation results coincide with experiment curve fairly |
