Magnetostrictive transducer, as a kind of high-efficiency transducer, has a broad application in the field of energy harvesting and sensor. However, the voltage generating performance of the transducer limits its application. This paper will endeavor to quantify the load-induced voltage of magnetostrictive transducer by developing a holistic theoretical model and deriving the corresponding analytical solution. On this basis, this paper proposed the concept of voltage sensitivity in transducer optimization, which could quantitatively analyze the normalized voltage generated by a unit excitation. Based on the theoretical simulation and experimental validation, the voltage sensitivities of magnetostrictive transducer under different mechanical loads are investigated. The parametric analysis will be conducted to further optimize the transducer structure to enhance its open-circuit and load voltage. The works of this paper could be instructive to guide magnetostrictive transducer design in sensing and energy harvesting applications.

“…Sablik and Jiles developed this model to analyze the magnetic mechanical coupling efect caused by stress and the coupling efect of magnetization and magnetostriction. Later, Jiles added the eddy current loss and other loss terms to the Jiles-Atherton hysteresis model to describe the magnetization of ferromagnet driven by a medium or a low frequency alternating magnetic feld [11,[16][17][18][19][20][21][22]. Wang applied this modifed model to describe the performance of the GMA, established a GMA dynamic model considering the eddy current efect and the stress' change, and identifed the model parameters by a hybrid genetic algorithm [5].…”

“…Te formulas are complex and need to be solved by programming, which is difcult for engineering practical applications. Terefore, an accurate and simple modeling method is very necessary for the engineering application of the GMA [20][21][22][23][24][25][26]. With the development of computer software, the physical modeling method based on simulation software is more and more welcomed by the engineers and technicians.…”

Due to the excellent performance, giant magnetostrictive actuator is used in the active vibration isolation control system. However, its hysteresis nonlinear dynamic model is too complex for engineering practical applications, so it is necessary to establish an accurate and easy-to-use model. Based on Simulink/Simcape, a magnetic circuit model and a nonlinear dynamic physical model of the giant magnetostrictive actuator are developed. In the optimization of the magnetic circuit, the uniform distribution and the magnetic energy utilization of the giant magnetostrictive actuator are taken as the optimization objective, and the design criteria of the magnetic circuit are given. The hysteresis performance between the current and the magnetization is analyzed by simulating the magnetic circuit model. From the perspective of energy conservation, a linear magnetostrictive model which can reflect the effects of the frequency doubling and preload is established. Finally, the accuracy of the nonlinear dynamic physical model for the giant magnetostrictive actuator is verified by an experiment. The results show that the physical model agrees well with the experiment results not only under the quasistatic operating conditions but also under dynamic operating conditions. The error of the output displacement of the GMA under step response is less than 0.6 μm.

“…Compared with piezoelectric materials and other traditional magnetostrictive materials, it has a large magnetostrictive strain, large output force, and fast response speed, which is widely used in precision actuation, active control, and other fields. Using GMM as the energy-transducing material to develop giant magnetostrictive actuators for injectors [4][5][6] is one of the research hotspots in recent years. With the continuous improvement of machining and manufacturing technology, many scholars [7,8] considered designing giant magnetostrictive actuators (GMAs) for direct-drive injectors.…”

The internal magnetic field characteristics of giant magnetostrictive actuators have an important influence on their output performance. Aiming at the deficiency of current scholars’ research, based on the electromagnetic theory and finite element method, this paper analyzes the magnetic field intensity on a giant magnetostrictive cylinder by using COMSOL Multiphysics software. Considering the inhomogeneity of magnetic field intensity along the radial direction of giant magnetostrictive cylinders, a new averaging method is introduced to calculate the magnetic field intensity in the axial section of the cylinder. The influence of the magnetic permeability of the displacement conversion mechanism (shell) and the size of the air gap inside the device on the magnetic field intensity of the giant magnetostrictive cylinder are analyzed. The prototype of the actuator is manufactured, and the correctness and accuracy of the simulation data are verified by experiments. In order to make the magnetic field on the cylinder strong and uniform, the displacement conversion mechanism and the shell should be made of low permeability and high permeability materials, respectively, and the air gap size should be reduced as much as possible under the condition of meeting the size requirement of the actuator pre-tightening force applying device.
