Abstract
The current paper studies an asymmetric bistable energy harvesting system which presents a very complex dynamics due to the presence of geometric and material nonlinearities. The objective here is to understand how the system parameters can change the dynamic behavior and identify which parameters most affect the harvested power. For this purpose, we compute basins of attraction for different asymmetry degrees, which are controlled by the bias angle of the system. In addition, we perform the global sensitivity analysis based on the Sobol' indices to identify the individual and joint contributions of each parameter in the energy recovering process.
