| Abstract: | In this paper,a typical structure was taken as the object of study,and the optimization of the vibration reduction was carried out from two aspects:the constraint layer and the stand-off layer.By using the general finite element software ANSYS and with the natural frequency,loss factor and frequency response curve as the evaluation parameters,factors influencing the dvnamic performances of the tvpical structure were analyzed. |
