| Abstract |
In this research, a new type of external periodic supports is proposed and analyzed for vibration control in the main structure. These supports are connected beams with different lengths and
boundary conditions periodically attached to the main structure. The Bloch theory combined with the
generalized differential quadrature rule (GDQR) method is implemented to obtain the vibration band
gaps. The impacts of the supports geometry on the first three bands are studied. Results indicate that
the starting frequency of first band is zero for all supports geometries. Results also indicate that there
are specific supports geometries in which the first and second bands or all three bands are attached to
each other. Forced vibration responses obtained via ANSYS show that strong vibration attenuation
occurs over the band gaps. All these results indicate that these new supports can be designed to strongly
absorb the vibration waves in the main structure over a very wide frequency interval starting from zero
frequency. The proposed periodic supports are suggested to be used for vibration control in the structures such as fluid-conveying pipes in practical applications. The forced responses implemented for
verification of the GDQR indicates that vibration of the structures made of connected elements can
be analyzed accurately and robustly using the GDQR. |
