Abstract
Linear dynamic vibration absorber can only suppress vibration of primary structure at one frequency. At other frequency it will amplify the vibration of primary structure. Nonlinear dynamic vibration absorber was introduced to increase the operational bandwidth of absorber. In this project, nonlinear dynamic vibration absorber was characterized using adjustable magnetic stiffness. This project starts with identification first vibration mode of primary structure. Then Operating Deflection Shape (ODS) for the first vibration mode was constructed. Then, nonlinear dynamic vibration absorber was characterized using three different variables. They are effect of gap between magnets, effect of input level from shaker and effect of length of absorber beam. Lastly, performance of nonlinear dynamic vibration absorber on primary structure was investigated at three different points and three different gap levels.
