| Popis: | In this study, flutter frequency of two joined cantilever beams used for energy harvesting has been investigated and optimized. Since there is a strong connection between the output power of the harvester and the system flutter frequency, maximizing flutter frequency increases the output energy significantly. The governing equations are developed using Euler–Bernoulli beam theory, and series method as an analytical approach is used for the solution. The obtained results were compared with the previous investigations, and effects of change in geometrical parameters are studied. The maximum flutter frequency is obtained using shape optimization for the tail beam. It is concluded that the optimized shape of the tail beam with constant length and volume causes significant increase in the flutter frequency, which improves the output power. |
