[Abstract]:In order to optimize the working characteristics of the giant magnetostrictive vibrator, the magnetic circuit structure of the exciter is studied and designed, and the corresponding structural parameters are obtained. The finite element model and dynamic mathematical model of the magnetic circuit of the vibrator are established by combining the Maxwell electromagnetics theory, and the image of the magnetic circuit structure and output characteristics of the magnets and the equivalent mass to the exciter is analyzed. The corresponding design scheme of the vibrator is obtained. The application data analysis shows that the vibration aging platform built with the exciter can meet the requirement of the exciting source of the aging workpiece.
