“…Several works dealing with MA present the attempt to mechanically amplify the total stroke, spanning from the crossbow geometry [44,[87][88][89] to hydraulic amplification through fluids [90][91][92], lever mechanisms [50,[93][94][95] and other more peculiar configurations [96][97][98].…”

Magnetostrictive actuators play an important role in the perception of usefulness of smart materials and devices. Their applications are potentially wider than that of piezoelectric actuators because of the higher energy density and intrinsic robustness. However, the non-negligible hysteresis and complexity of their characteristics make the design and control quite difficult and has limited their diffusion in industrial applications. Nevertheless, the scientific literature presents a wide offer of results in design and geometries, modeling and control that may be exploited for applications. This paper gives a reasoned review of the main results achieved in the literature about design, modeling and control of magnetostrictive actuators exploiting the direct effects of magnetostriction (Joule and Wiedemann). Some perspectives and challenges about magnetostrictive actuators development are also gathered.

“…MA can be part of hydraulic systems, acting as hydraulic valves (see, for example, [90,211,212]). Another popular application that, apparently, has not yet found wide spread commercial application is the use of MA in fuel injectors [10,96,97].…”

“…Bath University's Min Pan et al have used high-speed rotary valves to control the flow and pressure of a hydraulic supply [33]. Actuators made from piezoelectric materials [34][35][36][37], magnetostrictive materials [38][39][40], or shape memory alloys [41,42] provide different ideas for valve actuators. Nevertheless, novel form actuators designed by voice coil actuators [43,44], a stepping motor [45,46], and magnetorheological (MR) fluid [47] are booming with the development of Industry 4.0 [1].…”

Electro-hydraulic control valves are key hydraulic components for industrial applications and aerospace, which controls electro-hydraulic motion. With the development of automation, digital technology, and communication technology, electro-hydraulic control valves are becoming more digital, integrated, and intelligent in order to meet the requirements of Industry 4.0. This paper reviews the state of the art development for electro-hydraulic control valves and their related technologies. This review paper considers three aspects of state acquisition through sensors or indirect acquisition technologies, control strategies along with digital controllers and novel valves, and online maintenance through data interaction and fault diagnosis. The main features and development trends of electro-hydraulic control valves oriented to Industry 4.0 are discussed.

“…In the development of novel hydraulic servo valve (EHSV) serving in aerospace industry, giant magnetostrictive actuator (GMA) is a thriving device to generate micro stage displacement fast and precisely [1][2][3][4][5]. In many cases, a static bias field is employed in GMA to give a preelongation of the magnetostrictive rod when a bidirection stroke is required.…”

“…Generally, there are mainly two different analysis methods for magnetic field in ferromagnetic materials, namely, loop method and field method. Loop analysis is conducted based on the assumption that field distribution is homogeneous in radius span; therefore, the GMM rod could be modeled in its longitudinal direction as a network of magnetic circuits [24]; then Kirchhoff 's Laws are employed to calculate the field intensity and flux density; in traditional analysis, the magnetic circuit of GMA is regarded as a single magnetic loop [1,19], since in a classical tube-like PM configuration, the bias field is assumed to be uniformly distributed. Loop analysis denotes a lumped element method (LEM), in which the field calculated distribution is rough and noncontinuous, while this method is concise in structure, easily deducing an analytical solution, since only algebraic equations are resolved.…”

Many novel applications using giant magnetostrictive actuators (GMA) require their actuators output bidirectional strokes to be large enough to drive the load. In these cases, the sophisticated method to form such a sufficient bias field with minimum power and bulk consumption should be considered in the principal stage of GMA design. This paper concerns the methodology of bias field design for a specific GMA with stack PMs and GMMs (SGMA): both loop and field models for its bias field are established; the optimization method for given SGMA structure is outlined; a prototype is fabricated to verify the theory. Simulation and test results indicate that the bias field could be exerted more easily using SGMA structure; the modeling and optimization methodology for SGMA is valid in practical design.
