英文摘要：

A new type of electromagnetic active vibration absorbers is designed and analyzed to study the stability of its output force and the maximum of the output force.The magnetic circuit structure is simulated and analyzed by means of the equivalent magnetic circuit method,and the calculation formula of the output force of the electromagnetic actuator is obtained.The output force of the actuator is qualitatively analyzed for permanent magnets with different magnetic forces and coils of different diameters.The simulation results of the active vibration absorber are compared with those of the measured output force in the test.
