Abstract—In order to control the vibration of the specific frequency in the process of sheet metal parts, the dynamic vibration absorber is designed. First of all,obtain the target frequency which need to be controlled through modal analysis and determine the installation position of vibration absorber according to the vibration diagram; then get the equivalent mass and equivalent stiffness of the main system , and deduce the parameters of dynamic vibration absorber based on theory; make frequency response analysis on the sheet metal parts before and after the installation of dynamic vibration absorber in the Abaqus software to get the vibration displacement curve of reference point. The simulation results show that the amplitude of the vibration displacement of the reference point is obviously decreased after the installation of the dynamic absorber, which verifies the effectiveness of the vibration absorber.
