Magnetic Circuit Optimization Design and Simulation Analysis of Electromagnetic Inertial Actuator

Abstract

This paper introduces basic working principle of electromagnetic inertial actuators and establishes the mechanical model of actuator. With the method of three-level series permanent magnet, the actuator structure design was completed. According to the structure of the actuator, the magnetic circuit model of actuator was determined, and the design of magnetic circuit was completed. Through the comparison and analysis, the type of both ends of the cage was determined. The simulation analysis of actuators’ magnetic field was studied by using ANSYS, and then the parameters were optimized. The parameters of the optimal solution are concluded, and a way to the actuator parameters is found. This provides a theoretical basis for the production, development of the actuator, and provides a train of thought for the design of the new type of actuators in active vibration control.
