Title: Characteristics of dynamic vibration absorber shaped by steel beam with variable cross section rubber layer
Abstract: To control vibration of elastic structure,a new type dynamic vibration absorber is introduced to study its effect on mitigating vibration energy of structure theoretically and experimentally.While the elastic plate is certified as object to be controlled,the vibration model of plate fitted with multi composite beam at multi point is established by theory of power flow.After research on effect of single composite beam in energy absorbing,a method to obtain parameters of composite beam is formed and the advantage of composite beam in dissipating energy is proved.At the same moment,multi composite beam combined to decrease the vibration energy of plate is studied,the simulation results and experimental data shows that composite beams whose model frequencies are different with each other fitted at one point on plate can expand the bandwidth of absorber.While multi composite beam fitted at different point which is close to each other,the absorption of its combination is approximately equal to the union of absorption of each absorber in combination.It is concluded that the composite beams,which have advantages of wide bandwidth,great absorption and excellent extensibility,is fit to control vibration of plate with great effect,and its validity and feasibility is testified.
