In this paper, a high-power rotary ultrasonic machining system was proposed using a novel magnetostrictive material with giant magnetostriction (over 1000 ppm), high energy density, and fast response speed, namely Giant magnetostriction ultrasonic processing system (GMUPS). By applying the equivalent circuit of the GMUPS, the electromechanical conversion efficiency model was presented, and the effects...
To improve the capacity and reliability of a rotary ultrasonic machining system, a novel giant magnetostriction ultrasonic processing system (GMUPS) was designed. By using the equivalent circuit model, an optimal compensation model of the GMUPS, with and without a rotary transformer, was proposed. Considering the distributed capacitance of the coil at high frequency, the method of impedance analysis...
