摘　　要：温度是影响超磁致伸缩材料性能的主要原因;而磁滞损耗所产生的热量对材料的性能会造成很大影响。通过理论计算得到超磁致伸缩材料的磁滞损耗,为电流互感器的补偿提供基础,实现装置无磁饱和、精度高、速度快的目标。通过计算分析得到了基于Jiles-Atherton模型和BP-神经网络的磁滞模型参数;再利用四级四阶龙格库塔法进一步求解基于上述已求得参数的Jiles-Atherton磁滞模型,进而画出超磁致伸缩材料的磁滞回线求出对应的磁滞损耗。Temperature is the main character that influences the performance of giant magnetostrictive material.The heat generated by the hysteresis loss can have a significant effect on the material.A basis was provided for compensation of the current transformer through the calculated magnetic hysteresis loss of magnetostrictive materials to make the equipment have non-magnetic saturation,high precision and high speed.The hysteresis model parameters based on Jiles-Atherton model and BP-neural network are obtained by calculation and analysis.The Jiles-Atherton hysteresis model based on the above-mentioned parameters is further solved by using the fourth-order Runge-Kutta method.And then the hysteresis loop of the giant magnetostrictive material is drawn to find the corresponding hysteresis loss.
