| There are numerous ways to realize vibration absorbers. In thisstud y, a new method is proposed w...herein an elastomeric lattice is used. The geometrical configuration of the lattice is designed such that it transfers energy from the main system and is dissipated by the inherent material damping of the lattice material. The applicability of this system is numerically evaluated for pipelines by using two simple lattices whose geometries were optimized and the performances under harmonic loads compared with that of the theoretical optimal TMD. Eventhough they were capable of reducing the vibrations significantly, it was found to be less efficient at small mass ratios while at large mass ratios, the lattices performed similar to the theoretical optimal TMD. Nevertheless, in order to use such systems for pipelines or pipeline like structures such as chimneys, further studies are required using improved lattice configurations that can work efficiently for the whole range of mass ratios. |
