Vibration of structure usually accompanies noise and fatigue In this thesis we studied the wave propagation of a thin beam with multi-resonators numerically and experimentally It is demonstrated that the structure with internal resonators is capable of blocking the wave in particular frequency The cantilever-mass microstructures are used as the interior resonators Local resonance frequencies can be approximately estimated using a cantilever effective stiffness and mass system We used finite element software (ABAQUS) to simulate the propagation behavior of a thin beam with a single-resonator/dual-resonator system Furthermore we manufactured the thin beam with dual-resonator and conducted the vibrating experiment to verify the simulating results
