| dc.title | Dynamic analysis of a plate incorporating DVAs and tunable DVA design | en_US |
| dcterms.abstract | Performance of dynamic vibration absorbers (DVA) on a vibration plate has been investigated in present study. Therefore, a dynamic coupling model considering the interaction between multiple plate modes and multiple DVAs is derived. By developing a multimodal theory for describing the dynamic interaction between a plate and a DVA array, a rigorous analytical solution can be obtained. Based on this solution, performance of DVAs on a plate is proved to be effective. When the DVA is located at the optimal location, a maximum suppression effect can be achieved. In parallel, a design of DVA is proposed to implement a frequency and damping ratio tunable function. The smart device is built based on the prototype of a beam-mass system. A pair of porous disks is introduced to provide an adjustment damping. Performance of the device is experimentally proved to have a large adjustment frequency and an acceptable damping variation. | en_US |
