In order to expand the range actuator applicable, meet the higher dynamic magnification coefficient, and apply it to the environment of active control of structure response (ACSR), we designed a new type of resonant actuator in which the natural frequency is adjustable. The actuator based on the principle of resonance, is mainly composed of a designed beam structure, modulemass blocks, electromagnetic actuator, trestles, bearings, and so on. This paper designed the structure of the resonance actuator, conducted FEM simulation, performance test, and active vibration control simulation. In the fact, we can control the position of the mass to adjust natural frequency of it. Through the performance simulation, we calibrated the adjustable frequency range and transfer efficiency of it. Combined with the HHC algorithm and LabVIEW simulation, we apply it to the active vibration control. The results of simulation and test show that the new type of resonant actuator can be adjusted in the natural frequency of the structure, meet the requirements of the design for higher amplification coefficient, and according to different external excitation frequency, we can apply it to the ACSR by switching shifts of different resonance frequency.
