Application Cases

Giant Magnetostrictive Materials (GMM) are smart materials with magnetically controlled functional properties that enable bidirectional energy conversion between electromagnetic and mechanical energy. Compared to piezoelectric materials, shape memory alloys, and electrostrictive materials, GMMs offer higher energy conversion efficiency, larger strain rates, lower driving voltages, faster response times, and broader operating frequency bands. Actuators developed using GMMs are characterized by their simple structure, high output force, and rapid response, making them highly promising for applications in precision positioning, active vibration control, and fluid control.

ATA-3000/300 Series Power Amplifiers are based on AB class amplification circuits, featuring low distortion and high stability. They have a maximum bandwidth of up to 120 kHz, a maximum output voltage of up to 100 Vpp, and a maximum output current of up to 40 A. These amplifiers are widely used in testing various magnetic materials and driving magnetostrictive transducers.

Experiment Name: Structural Optimization of Giant Magnetostrictive Actuators Based on the BP-NSGA-II Algorithm

Experiment Principle:A Giant Magnetostrictive Actuator (GMA) is a novel type of actuator whose main driving component is made of Giant Magnetostrictive Material (GMM). The working principle of a GMA is based on the magnetostrictive effect: when current passes through a coil, a magnetic field is generated inside the coil according to the principle of electromagnetic induction, causing the GMM rod inside the coil to change length. This, in turn, drives the output rod to produce a certain displacement and force.

Experiment Process:A signal generator produces a sinusoidal AC signal, which is amplified by the ATA-309 power amplifier to drive the vibration of the giant magnetostrictive actuator. A laser displacement sensor, oscilloscope, data acquisition card, and display device, in conjunction with a PC, complete the display, acquisition, processing, and subsequent analysis of the data.
