| 摘 要： | 超磁致伸缩致动器的输入磁场与输出应变存在着磁滞非线性。为了控制及使用致动器，必须建立其准确的数学模型。该文基于Jiles—Atherton磁滞模型、二次畴转模型、非线性压磁方程和致动器结构动力学原理，建立了超磁致伸缩致动器的磁滞非线性动态模型。应用该模型对致动器的输出应变进行计算，计算结果与实验结果符合较好，验证了模型的正确性和实用性。

| Abstract: | The relation between input magnetic field and output strain by the giant magnetostrictive actuators exhibits nonlinearities and hysteresis.To control and use the actuators, it is necessary to establish an accurate model of the actuators. This paper founded hysteretic and nonlinear dynamic model for the actuators based on the Jiles-Atherton hysteretic model , the quadratic domain rotation model, the hysteretic nonlinearity equation and the actuator structure dynamics principle. The output strain for a magnetostrictive actuator has been calculated. It is found that the calculating results are in a good agreement with the experimental ones. This indicates the integrated model's validity and practicability . |
