Established a double-oscillator multi-frequency dynamic absorber based on single-oscillator model in order to break through the limitation of single-frequency vibration absorption and reduce the vibration response of thin plate structure. Firstly, described the double-oscillator dynamic absorber model and applied spring-mass unit to constitute the absorption system for absorbing vibration energy. Then introduced the model parameter determination scheme. Finally simulated and analyzed the absorbing effect of the double-oscillator model by finite element sofware. The results show that the designed model effectively absorb vibration energy, and the structure is simple and easy to install.
